When an annotation constructor value parameter is annotated with the
very same annotation, FIR2IR went in an infinite loop when trying
to generate it.
To fix this, the constructor is added to the Fir2IrDeclarationStorage
cache before generating the value parameters.
To accommodate for the missing parameters, the value arguments count
is determined using the FIR.
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.

Also add test to loadJava folder with annotations default values that
verifies metadata loading
This fixes a false positive TYPE_PARAMETER_IS_NOT_AN_EXPRESSION when
a type parameter and some member, static or companion declaration have
the same name and referred to inside a class.
#KT-58028 Fixed
When suspend function type is serialized, there is special logic that
adds Continuation parameter, before doing so, type-aliases has to be
expanded, attributes for resulting type should also derive from
expanded type

In DeserializedClassDescriptor and MemberDeserializer, only the
`contextReceiverTypeList` field was used, and not
`contextReceiverTypeIdList` which is used when `-Xuse-type-table` is
enabled. The convention is to use a bunch of utilities declared in
`protoTypeTableUtil.kt` which deal with both methods of reading types.
Also, simplify the deserialization code in FIR (which was correct for
some reason).
This is a partial revert of e857966edb.
Specifically, behavior is restored in the old backend, which will allow
to support language version 1.3, where this language feature was not
enabled yet. There are no changes in the JVM IR backend, because to
enable JVM IR with LV 1.3, you need to pass the compiler argument
`-Xuse-ir` which is not stable and we don't guarantee anything about it.

so that defaults are available to synthetic implementations.
#KT-48181 Fixed
Implementation is for JVM IR; other backends & FIR need to be supported
separately.
KotlinJvmBinaryClass.AnnotationArrayArgumentVisitor didn't cover the
case when the element type is an Annotation. Therefore, when the
compiler read an array of annotations from JVM binary classes built from
Kotlin sources, it got an empty array regardless of what was written in
the bytecode.
For example, Foo.value below is read as an empty array when SomeClass
resides in another Kotlin module.
@Foo(
value = [Bar(1), Bar(2)]
)
class SomeClass
This makes sense because this mode is the default in the production
compiler. Forgetting to enable it where necessary led to different
bizarre test failures, see for example changes around 3fee84b966 and
