It acts as a workaround for the case when build tools or dependencies
are compiled with latest 'kotlin-stdlib' version, but at a runtime older
'kotlin-stdlib' is provided, which does not know about new
`EnumEntries`.

IC: Compute symbols impacted by classpath changes
Incremental compilation has 4 key steps:
1. Compile changed/impacted files
2. Detect symbols that have changed after compiling
3. Detect symbols that are impacted by the changed symbols
4. Based on the changed-or-impacted symbols, identify files that need
to be recompiled. Go back to step 1.
Normally, step 2 and 3 are done together when the changed symbols
and impacted symbols are in the same module.
However, if the changed symbols and impacted symbols are in different
modules (e.g., a `Subclass` in lib1 extends a `Superclass` in lib2),
we currently do not compute symbols in the current module that are
impacted by changes in another module (step 3 above).
This is the case for both the new IC and the old IC.
In this commit, we will compute impacted symbols for the new IC. We can
fix the old IC later if necessary (they can't be fixed together easily).
Test: Added BaseIncrementalCompilationMultiProjectIT.testChangeInterfaceInLib

Historically flag was enabled for Gradle projects, but we don't have fir-based JavaTracker for the K2 compiler for now, so we need to use a fallback strategy.
Note: it was disabled for tests with K2
Note2: after adding a fir-based java classes tracker this value should be set to true (KT-57147)

This is required to be able to compile KGP and it's dependencies which
set LV to 1.4 when repo will use LV 1.9. This caused by the change how
enums are compiled (KT-48872).
If you need to mute a test for Gradle IC, the only way is to add exclude pattern and regenerate tests aka remove unnecessary tests. But the filter is absolute, so if you have the same test name in different subfolders (e.g. `pureKotlin/classRemoved/` and `classHierarchyAffected/classRemoved`) you cannot disable only one of them. This commit adds logic to specify which name pattern in which subfolder should be excluded
Currently, FIR compilation of `const val b: Byte = 50 + 50` shows an error, but old compiler doesn't (it shows only warning). Since this is an incremental test, it should not be affected by compiler errors, but should only test for .kt usage without recompilation.

This reverts commit c4a29651 as it is no longer needed after IC fix: `5ba3053e` "[IC] Do not report recompilation of non-existing files", because now fix-ic-build.log duplicates the main build.log
#KT-54991 In Progress
If typealias is defined in a separate file, then after changing some base types, an incremental compilation of Kotlin could not find all affected files, because of lack of information, which it can not get on the class file analyzing phase. FIR provides a new approach to IC compilation: now we can run the frontend several times, which allows us to obtain all necessary information and use it to mark all affected files for recompilation.

A LookupSymbol should only refer to either a class, a class member, or a
package member.
When a LookupSymbol refers to a file facade (e.g.,
LookupSymbol(name="FooKt", scope="com.example")), it is redundant as it
doesn't impact the IC analysis to find files to recompile.
Previously, the new IC (ClasspathChangesComputer) would fail when
detecting that IncrementalJvmCache reported these redundant
LookupSymbols. With this change, the new IC will just ignore them.
Note: A better approach would be to fix IncrementalJvmCache to not
report these LookupSymbols, but it will require some significant
cleanup/refactoring work, so we can consider it later.
Test: New KotlinOnlyClasspathChangesComputerTest.testRenameFileFacade

Make the code more readable and address a small issue where we
did not close caches when returning `ICResult.RequiresRebuild`
(it was not exactly a correctness issue because we would recompile
non-incrementally in that case).
^KT-55709 In progress (This is a follow-up on a previous change for this
bug)
- Move out getAnalyzerServices from FirFrontendFacade to TestSetupUtils
- Simplify DependencyListForCliModule. Now it takes BinaryModuleData as input
- FirOutArtifact contains several FirOutputArtifactPart
- Simplify FirFrontendFacade
Previously, we didn't close caches if incremental compilation failed.
The assumption was that we would fall back to non-incremental
compilation, where it shouldn't matter whether caches were closed or not
as non-incremental compilation should be able to recover from a
corrupted state of the caches.
However, this choice might have caused issues such as KT-55709 where
non-incremental compilation fails after fallback.
In this commit, we will now always close the caches before falling back,
just to be safe.
TODO:
1. We'll need to verify whether not closing the caches was the actual
cause of KT-55709, and that this commit fixes it.
2. Even if this commit fixes the issue, we'll need to see why
non-incremental compilation fails to recover from unclosed caches
(it would remain unsafe if that was not addressed).
^KT-55709 In progress (see TODO #1 above)
Optional-expectation annotations which have an actual counterpart should
have never been serialized to the kotlin_module's proto. See for example
the original (correct) implementation in the old JVM backend in
`PackageCodegenImpl.addDescriptorToOptionalAnnotationsIfNeeded`.
