In the FIR generator, the `AbstractElement` class was used to
represent either an element type without type arguments applied
(using the `Element` subclass), or an element type with applied type
arguments (using the `ElementWithArguments` subclass).
Instead, it is more logical to use the `Element` class to always
represent a non-parameterized element type, and for a parameterized
element type use the `ElementRef` class, just like we do
in the IR generator.
In these cases we have a `FirVarargArgumentsExpression`
with a `FirNamedArgumentExpression` inside as its first
argument, which, in turn, has a `FirArrayLiteral`
argument.

...accidental use of tree-specific implementation instead of common one.
Actually, I stepped on this rake myself in next commit, when
accidentally imported function from `PsiSourceNavigator`.
^KT-59978
After this commit there are three different versions of
IR source range tests: classic (K1), FIR/PSI (K2), FIR/LT (K2).
Since 5 tests behave differently for FIR/PSI and FIR/LT,
in this commit their test data was set to FIR/LT state,
so relevant 5 tests are failing for FIR/PSI right now.
They will be fixed in two subsequent commits

- The semantics of a non-static declared member scope should be as
follows: For a variable `c: C` of class type `C`, the declared member
scope should contain all members `x` accessible as `c.x` (visibility
notwithstanding) which are *also* explicitly declared in `C`.
- Classifiers are not accessible as properties of a variable `c`, only
as static members of the class `C` itself, so non-static declared
member scopes should not contain any classifiers.

- Member scopes already don't contain static callables, only their
static member scope counterparts. However, declared member scopes
contained both non-static and static callables, which was confusing to
users. See for example KT-61255.
- Now declared member scopes only contain non-static callables and
static declared member scopes only contain static callables.
- In `KtFirScopeProvider`, the new implementation is different for
Kotlin and Java classes, because the standard declared member scope
doesn't work for Java. Instead, we have to get the Java *enhancement*
scopes from `JavaScopeProvider`. Unfortunately, `JavaScopeProvider`
doesn't have a direct enhancement declared member scope. This results
in a somewhat complex scope structure with the declared members filter
scope around the use-site/static Java enhancement scope, but since the
declared members filtering scope properly reduces the set of callable
names and scopes in general are cached, this shouldn't be an issue.
- `getCombinedDeclaredMemberScope` is introduced as a separate public
function because for Kotlin scopes, we don't actually have to create a
combined scope, as the non-static and static scopes are just filters
around a combined declared member scope provided by the compiler. It's
also important to have a convenient function to get the combined
declared member scope, because some usages explicitly want access to
all declared members (such as symbol light classes).
- This commit also fixes KT-61901, because
`getFirJavaDeclaredMemberScope` now provides a proper static scope for
Java classes, which will be accessible via the combined declared
member scope as well.

When the left-hand side of an equality comparison is known to be a
String, and the equality condition resolves to true, then the right-hand
side can be smart-cast to a String as well. This was working for String
expressions on the left-hand side but not for String constants.

Review: https://jetbrains.team/p/kt/reviews/12279/files
Motivation: make sure that cases like KT-62027 won't happen again
Review: https://jetbrains.team/p/kt/reviews/12279/files
Now it's responsibility of the
`createExpectActualTypeParameterSubstitutor` calller to think about the
case when parameters size isn't equal. You must not be able to create a
substitutor if type parameters sizes are not equal
Improvement in `createExpectActualTypeParameterSubstitutor` API also
improves
`AbstractExpectActualCompatibilityChecker.getCallablesCompatibility`
API.
Because suppose that you accidentally created a redundant wrapping
substitutor => you need to handle the case of not equal type parameters
size on the call site => you start thinking why you should do that on
the call site? It must be a responsibility of
`getCallablesCompatibility` => you realize that you created a redundant
wrapping substitutor
When type parameters size doesn't match, it's better to pass `null`
instead of a parentSubstitutor. Before this commit we were creating an
invalid substitutor. Who knows what can go wrong because of that further
along the execution

Review: https://jetbrains.team/p/kt/reviews/12279/files
Motivation for the commit: There is no user report or anything. It's not
known whether these invalid substitutors were causing problems. I just
noticed this problem while doing substitutor API refactoring (see the
next commit).
Note: `ExpectedActualResolver.matchActualCallableAgainstPotentialExpects`
has the same problem. But since it's K1 I won't touch it
Anonymous functions (lambdas) are not allowed as annotation arguments.
However, because it is still possible to parse code written this way, it
must be handled without exception. So ignore these expressions when
processing annotation arguments.
#KT-59565 Fixed
Scopes may return private symbols from
supertypes, they should not clash with
symbols from the current class.
For example, see:
`FirLightTreeBlackBoxCodegenWithIrFakeOverrideGeneratorTestGenerated.FakeOverride#testPrivateFakeOverrides1`
Lombok shouldn't generate functions if the
user has defined explicit ones.
In K1 generated functions are not really
added to the declared members scope.
