FirConstExpression is usually confused with "constant" calculations,
while in fact, it just denotes a simple literal expression
and `1 + 1` isn't represented by a FirConstExpression.

`FirDeserializedEnumAccessExpression` requires session to build proper
reference, so it's important to have it in all utilities, which may
pass this element as input

On-air analysis only worked correctly inside declaration bodies, and
required special handling ('analyzeInDependedAnalysisSession()').
Dangling files, the on-air replacement, works seamlessly, and it is
available in all contexts.
The error-level enhancement is kept as warning-level and a new
LanguageFeature is introduced to turn the warning into an error.

(cherry picked from commit 371b1eb3d5)
N.B. This implementation does not 100% prevent conflicts or resolve
alterations when shortening functions.
To guarantee that,
we would need to carefully consider all the references in the file,
and to check whether they have changed their resolve in the presence
of a new import.
This is not trivial and will be approached separately under a different
task.

- KT-62895 cannot be reproduced on the Analysis API side. Still, it is
useful to add tests here for better coverage in the future.
- The reason is likely that Analysis API tests specifically use
`SealedClassesInheritorsCaclulatorPreAnalysisHandler` to compute
sealed class inheritors (which are usually the breaking point for
problems in `when` exhaustiveness checking), so the tests do not use
the production implementation. See KT-64505 for future work on this
problem.

Motivation: AMBIGUOUS_ACTUALS can't be reported on frontend (because it
requires expect to actual mapping, but the mapping is only available on
backend)

This way, even if the whole qualifier is not selected, but some of its
parts are, the reference shortener will correctly find and shorten
those parts

In the 'IGNORE_SELF' mode, dangling files don't have their own
declarations in providers. As a result, all references there resolve to
declarations of the original file. It is conceptually similar to that we
had in on-air resolve, however, now it's possible to work with the whole
content of the in-memory 'FirFile'.
As it can be seen in 'ProjectStructureProvider.kt'
(KtFile.danglingFileResolutionMode), the 'IGNORE_SELF' mode is
automatically applied for non-physical files with an original file being
set. For other scenarios, now there is a new 'analyzeCopy()' function
that allows to pass the analysis mode explicitly.
PSI events do not arrive for dangling files with no backing
'VirtualFile', so its partial invalidation becomes non-trivial.
In the change, a short-living cache is implemented for these 'unstable'
dangling files.
Dangling files are copies of files in the context module, or just
depend on it. In any way, dangling file modules see all internals of
the context module.
This commit introduces dangling file modules, which may be either
code fragments or ordinary Kotlin files. As before, code fragments are
analyzed against some context element, however ordinary files only
have a context module.
Code fragments can also have a dangling file module as a contextual one,
including other code fragment. This is done to support potential usages
in completion, intentions and refactorings.
Utilize `FirSamResolver` to obtain the potential SAM constructor
from the classifier
Also, accept K2_SYNTHETIC_RESOLVED in the `resolveUnqualifiedAccess`,
since this is the kind of resolve success which corresponds to the
SAM constructor call resolution
