Moved pathExists from SysCalls to path.h.
In ULTs, use unchanged pathExists and mock stat, getFileAttributesA instead.
Add Windows and Linux ULTs for pathExists.

Added support for new Compiler Cache
environment variables in Level Zero.
Moved
`opencl/source/compiler_interface/default_cache_config.cpp`
`level_zero/core/source/compiler_interface/default_cache_config.cpp`
to shared directory
`source/compiler_interface/default_cache_config.cpp`
Switched enabling cache by default from per OS to per API.
Changed default state of cl_cache in Level Zero to disabled.

Refactored eviction mechanism works as follows:
- eviction is needed only if
total size of cache binaries + size of the new binary exceed cache limit
- single evition call removes files with a summed size of 1/3 of the cache limit
- if new binary can not fit in the cache size limit
even after eviction, it will not be saved
- cache limit applies only to
files in cache directory with .cl_cache/.l0_cache extension.
Only these files are counted and only these files are removed

What's changed:
- Add early return when open existing config
fails due to different error than `ERROR_FILE_NOT_FOUND`
- Swich `ReadFileEx` to `ReadFile`
- Add `SetFilePointer` to make sure we're reading
from the beginning of the file
- Pass `overlapped` to `WriteFile` to make sure
we're writing from the beginning of the file

config.file should not be created manually by the user.
In a scenaro when the user manually creates an empty config.file,
then reading data from this file ends with failure,
because the file is empty.
Such scenario completely freezes the cache creation
until the user manually deletes the empty config file.
This patch fixes such freeze by automatically deleting config
if read fails with ERROR_HANDLE_EOF error.
Patch applies to windows only.

Changes:
- replaced registry keys with environment variables
for cl_cache in OCL
- added compiler cache helpers
- implemented support for new env vars on Windows
- added tests
New env vars mechanism works as follows:
If `PERSISTENT_CACHE` is set,
driver checks if `NEO_CACHE_DIR` is set.
If `NEO_CACHE_DIR` is not set,
driver uses `%LocalAppData%\NEO\neo_compiler_cache`
as `cl_cache` destination folder.
If `NEO_CACHE_DIR` is not set and `%LocalAppData%`
path could not be obtained,
compiler cache is disabled.
In the current Windows implementation,
special characters in the folder path are not supported.

Use the same file `os_handle.h` on both
Linux and Windows.
Change implementation of `HandleType` -> `UnifiedHandle` to
`std::variant<int, void *>`
use `int` on Linux
use `void *` on Windows

This patch add new environment variables to control compiler cache.
Works as follow: If persistent cache is set driver check if NEO_CACHE_DIR
is set. If not then driver checks XDG_CACHE_HOME - If exists
then driver create neo_compiler_cache folder, if
not then driver checks HOME directory. If each NEO_CACHE_DIR,
XDG_CACHE_HOME and HOME are not set then compiler cache is disabled.
Current support is for Linux only.
