- Allow 'lateinit' for inline classes which underlying type
is suitable for 'lateinit'
- K2: report all problems related to 'lateinit' modifier
^KT-55052: Fixed
- Ensure that typed equals parameter's type is a star projection of
corresponding inline class
- Make possible to declare typed equals that returns 'Nothing'
- Forbid type parameters in typed equals operator declaration

Before, the only way of getting analyzable elements was to create an
analyzable file by using 'createAnalyzableFile()'. So made all utilities
available in 'KtPsiFactory' useless as they delegate to 'createFile()'
that always set the 'doNotAnalyze' flag.
The new behavior is to pass the 'analysisContext' instead if it is
passed to the 'KtPsiFactory' constructor.
The newly appeared API is going to be used in the Kotlin's UAST
implementation.
The `getSourceForArgument` method should be in the interface,
but adding it is a breaking change for Java usages,
since the module is not built with -Xjvm-default (KT-54749).
Move the method to an extension. This doesn't change the behavior,
since it was only ever called on LazyAnnotationDescriptor.
Lazy computation in publication mode may lead to running of init code
many times in parallel, and it actually happens in IDE.
Instead, we stick to the option which is used for lazy computations
all across compiler code.
This has no effect on behavior, but will fix a binary compatibility
problem with Compose.

In K1, within SubstitutingScope we approximate almost all the types
containing captured types are being approximated to either a lower or
an upper bound.
While mostly, it's being done correctly there are some problems with
approximations for flexible types
So, the parameter's type of A<in Any>::foo is approximated to Inv<in Any!>,
thus allowing to use Inv<*>, while it's obviously unsound.
NB: For the similar example, in B, there are regular TYPE_MISMATCH
because parameter for B<in Any>::foo is approximated to Nothing
Also, it's important to say that
- in K2 everything works because we don't use type approximation there
- approximation algorithm that works incorrectly is only being used in K1
^KT-54332 Fixed
'equals' from any made available for overriding in inline classes
'typed' equals made available for definition in inline classes
'typed' equals definition made compulsory if 'untyped' is overridden
'operator' keyword is allowed in 'typed' equals definition
^KT-24874: Fixed
Report an error that inference will change and type has to be provided
manually in other language versions, since the current behavior is an
unsoundness that can cause runtime NPEs while the new behavior may
silently change overload resolution.
