This is the way it works in K1.

Why did the problem existed?
At first, lambdas were analyzed with suspend function expected type,
because it's the WHEN-case and we propagate expected type info to
the branches.
Then, after the lambdas was introduced to the containing inference
system, we're creating ResolvedLambdaAtom using the information
from analyzed lambda's shape, but didn't use known lambda resulting
type (from which we might infer FunctionTypeKind).
So, the fix is just using that already obtained information.

The only case when behavior is change is described at
computeNonTrivialTypeArgumentForScopeSubstitutor
The idea is to avoid depending on the presence of @UnsafeVariance
and instead approximate captured types in covariant argument positions
before building substitution scopes
It's correct because for Captured(*) <: Supertype,
Out<Captured(*)> <: Out<Supertype> and when we've got @UnsafeVariance
value parameters at Out, it's ok to allow passing Supertype there.

This fixes an issue where an actual class from an intermediate module
has more supertypes than its expect declaration which leads to a
false-positive resolution error because a type reference resolves to the
expect class. The fix is to sort the dependencies topologically from
"most actual" to "most expect" when creating the list of symbol
providers.

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.

Basically, this commit reworks eraseToUpperBound* stuff
Instead of a bunch of vague flags, we introduce two modes
(rawTypes/intersection emptiness checker) which defined those flags.
Also, it makes choosing `eraseArgumentsDeeply` option always because
that how it works in K1 and also use invariant projection inside
`eraseArgumentsDeeply` for raw types for the same reason.

These tests won't be FIR_IDENTICAL after the next commit. That's why I
split them prematurely. This allows me to have a nicer diff in `2/2`
commit.
In scope of KT-15470
Review: https://jetbrains.team/p/kt/reviews/9250
so the check is functionally the same as in K1.

One of the tests introduced here (javaMappedCtors) revealed an
additional issue, filed as KT-57368
The idea of the fix is just unwrapping flexible version of type alias,
before creating a not-nullable version for safe-call subject.
Otherwise, it was remained to be JsExpressionResult after applying
makeConeTypeDefinitelyNotNullOrNotNull (and the type is still nullable)
^KT-57190 Fixed
During implicit body resolve phase, we can encounter a reference to a
not yet resolved Kotlin class that inherits a synthetic property from a
Java class. In that case, resolve the return type in
FirSyntheticPropertiesScope.
