CoreJrtFileSystem uses JrtFileSystemProvider provider to read contents
of jrt-fs from JDK
Implementation of FileSystems.newFileSystem causes metaspace memory leak
that wasn't fixed until JDK 17, see
https://bugs.openjdk.java.net/browse/JDK-8260621
When FileSystems.newFileSystem used to create jrt-fs on JDK9 with
provided java.home value it creates new ClassLoader under-the-hood,
which subsequently leaks due to aforementioned bug
Remove conditional usage of `java.home` + FileSystems.newFileSystem and
switch to use jrt-fs classloader cache regardless of
compiler runtime JDK to reduce classloader leaks

If a developer interrupts (kill gradle process) a compilation process or
an internal error interrupts the compilation process,
the incremental cache files may be corrupted.
The patch creates a special guard file, which allows detecting
if the previous compilation was not successful,
and in case of any issues drops the incremental cache files.

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).
Scope for incremental compilation refers to binaries from previous step
of IC. It is used not only in IC context itself, but also it is
subtracted from original libraries scope. Before previous commit there
was such scheme:
1. create incremental compilation context for files of specific session
2. subtract IC scope from main libraries scope
3. use updated libraries scope to create library session
4. create all needed source session(s)
So here was a side effect of creating new IC context, which
1. is smelling code, because it increases mind complexity
2. hard to implement with new session utilities
So to fix this problem this commit changes the scheme above:
1. create IC scope and modify libraries scope
2. create libraries session
3. create source session(s) and IC context for them
make write protection directly in properties
it creates no additional wrapper with the link to the containing class
for ij project, this reduces memory usage for ~15 mb

In scope of: KT-55082
Because this version isn't used for anything. We have KotlinAbiVersion
to version the IR format.
Also introduce -Xsave-llvm-ir-directory argument
that should be used instead of -Xtemporary-files-dir
as a location for LLVM IR from phases.
Motivation for this change: it is simpler to implement
and unties LLVM actions from the awful TempFiles class.
Fix merge conflict related to renaming of one of the tests
Regenerate tests affected by previous commit
Fix merge conflict related to renaming of one of the tests
Improve wording of the `-Xuse-k2 -language-version 1.*` CLI warning
Improve wording of LV2.0-specific CLI warnings some more
Fix output of one of the tests for -Xuse-k2 deprecation
Tweak wording of LV2.0-specific CLI warnings
* make it clear in every warning that -Xuse-k2 is deprecated
* add a reminder to remove -Xuse-k2 for `-Xuse-k2 -language-version 2.0`
* add both possibly wanted fixes for `-Xuse-k2 -language-version 1.*`
Remove deprecated -Xuse-k2 flag from one of the tests
