This commit adds missing pieces for the puzzle:
Annotation instantiation feature uses IrProperty's initializer to instantiate
properties from other modules that have default values which weren't
specified on call site.
To support this feature properly, Fir2IrVisitor should fill LazyIrProperty's
backing field initializer with information from Fir.
To get this information into Fir, FirMemberDeserializer should be able to read
it from KotlinJvmBinaryClass with AnnotationLoaderVisitorImpl. (klibs are unsupported for now)
There's a catch with enum entries references: we can't access session.SymbolProvider to resolve it
because we're still at the deserialization stage, and it can cause StackOverflow if enum is nested in the
same class (see RequiresOptIn.Level). To mitigate this, a new FirEnumEntryDeserializedAccessExpression is produced
instead; it is later replaced with the correct reference in the Fir2IrVisitor.
^KT-58137 Fixed
Also add test to loadJava folder with annotations default values that
verifies metadata loading
It's obviously expected that all overridden, not only direct ones
are considered
While it likely changes the behavior and some tests are expected to be
changed, original intention was to fix the behavior for other usages
(see later commits) and the part with tests are postponed with KT-58636

Also, this change adds SinceKotlin and Java.Deprecated to this phase
It fixes some problems with API_NOT_AVAILABLE, so now it is closer to K1

Notice on `DebugSymbolRenderer`:
stub based deserializer sets source directly,
but it's available in IDE mode only.
Thus, standalone and IDE tests have different results.
In order to avoid this, sources for compiled code are explicitly ignored
Notice on distinct callables:
for a file which belong to multiple libraries, decompiled code would be build per library.
In order to avoid ambiguity errors for members in that file,
we need to distinct provided elements by origins
failed test from IJ repo:
FirReferenceResolveWithCrossLibTestGenerated#testSetWithTypeParameters
The compiler should only report diagnostics for
comparisons over builtins and identity-less types,
other incompatibilities should be reported
via inspections.
It's ok that in `equalityChecksOnIntegerTypes`
instead of `EQUALITY_NOT_APPLICABLE_WARNING` we get
`EQUALITY_NOT_APPLICABLE`, because
`ProperEqualityChecksInBuilderInferenceCalls`
is already active by default.
This change also replaces the notion of a representative superclass
with the least upper bound.
This makes complex types like
intersection/flexible transparent to
RULES1-based compatibility checks.
One way to look at it is to think
that this is an automatic way of handling
type parameters: automatic picking of
"interesting" bounds, and checking them against one another.
Note that `TypeIntersector.intersectTypes`
for `Int` and `T` where `T` is a type parameter
may return both `{Int & T}` or `null`
depending on `T`-s bounds. At the same time,
for type parameters `T` and `K` it will
always return `{T & K}`.
`ConeTypeIntersector.intersectTypes`, on the
other hand, will always return `{Int & T}`
irrespectively of the bounds. Meaning, the two
intersectors differ in corner cases.
`lowerBoundIfFlexible` call in `isLiterallyTypeParameter` is backed by
the `equalityOfFlexibleTypeParameters` test.

In a lot of cases, when we want to process the
declaration in scope, it should be resolved to at least TYPES phase.
To avoid doing it manually in all our variety of scopes, we do it when the scope it created.
It was implicitly working manually before as lazy resolve did a lot of extra work
on resolving a declaration it was not supposed to resolve.
Now it's not the case, and we have to explicitly resolve all the declarations we need.

Otherwise, when we come to `ClassCodegen.kt:173
for `GradleActionTest` and check
`FUN FAKE_OVERRIDE name:<get-project>`,
we then go to `JvmSignatureClashDetector.kt:37`,
and call `mapRawSignature(overriddenFunction)`
which ignores the original `@JvmName`.
It does so because it relies on the property copy
which forgets to copy the getter, but
`@get:JvmName` is stored in it.
Extra when-branches for `FAKE_OVERRIDE` are needed,
because otherwise the annotations would not
be copied in `Fir2IrDeclarationStorage.kt:723`.
Extra when-branches for `DELEGATED_MEMBER` are
needed, because otherwise the generated IR changes
in some tests. For example, see:
`FirLightTreeIrTextTestGenerated.Declarations.testKt35550`.
The `assumesBackingField`-related change is backed by
the `FirLightTreeIrTextTestGenerated.Stubs.testJavaEnum` test.
`this.body = null` ensures the resulting IR
matches K1.
The change in `FirImplicitBodyResolve.kt` is needed,
because otherwise the bootstrap compiler fails at
`:compiler:frontend:compileKotlin`,
but I didn't come up with a smaller test for it.
If we don't make an explicit accessor copy,
then when we later create a `Fir2IrLazyPropertyAccessor`
for the fake override getter, it's `fir` will
be a reference to the `FirProperty`, not `FirPropertyAccessor`.
That's why `DumpIrTreeVisitor` will render `IntrinsicConstEvaluation` as
a getter annotation as well.
`FirPsiIrTextTestGenerated.testDelegatedGenericImplementation`
renders type parameters from `<get-x>`,
because when assigning `extensionReceiverParameter`
of the setter `<set-x>` we come to
`Fir2IrClassifierStorage.kt:638`,
and in this cache there's the parameter with
the `<get-x>` parent.
Note that `typeContext.origin == DEFAULT` in
`getCachedIrTypeParameter`.
It's `DEFAULT` because at the line `Fir2IrDeclarationStorage.kt:335`
the `function` variable is `null` (because there's no setter).
The change in `declarationAttributes.kt` is backed
by the `FirPsiIrTextTestGenerated.testKt45853` test.

- Dependency symbol providers contained a lot of useless
`FirExtensionSyntheticFunctionInterfaceProvider`s, because such a
provider only generates function classes from compiler plugins. If
there aren't any such `FunctionTypeKind`s in the session, there is no
need to even add the provider.
- `FirExtensionSyntheticFunctionInterfaceProvider`s that are added to
the list of dependency providers despite this optimization will now be
combined in `LLFirCombinedSyntheticFunctionSymbolProvider`. It checks
`ClassId` heuristics once, which is more efficient than checking them
in every provider separately.
with dedicated opt-in language feature and special
annotation or module capability.
Not intended for a general use, solves specific K/N
scenario with interop libs.

The basic idea is that during deserialization/loading compiled
Java classes, there might be some of the dependencies absent that
are referenced from enum arguments in annotations.
Such situation is not considered as totally ill-formed, thus supporting
it, allowing to read the names of mentioned in the annotation argument
might be useful for Java enhancement
^KT-56656 In Progress
Remove a bunch of custom logic to determine when a callable reference is
bound or not (and hence mustn't have a receiver). Instead, a helper
extension is introduced to determine when a callable reference is bound
by checking if dispatch/extensionReceiver is not FirNoReceiver and the
referenced member is not static.
