getLoadedLibVersion is intended for reading version of a library that was
already loaded into the process prior to this call (i.e. new instance of
the library willnot be loaded).
Note: Currently, only windows version of this functionality is implemented.

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

This is an OS behavior to have failed an allocation with a
const buffer backing storage (PAGE_READONLY attribute set)
ReadOnly flag allows to create allocation with read-only
backing storage

Allow custom values for different test types, i.e. ULT, AUB, etc. can
have custom timeout by using e.g.: NEO_{ULT,AUB,...}_ITERATION_MAX_TIME.
Old behavior with reading NEO_ULT_ITERATION_MAX_TIME for each test type
is preserved but new envirnoment variable has precedence.

- Change the heap/pageSize used based on the size of the reservation
required and the device heaps available.
- Return the page size required based on the size requested by the user
for virtual reservation and the devices on the system.
- Check the size passed in by the user in memory map and physical memory
allocation is valid for the heap and page size that is required.

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

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.

By default prefer allocating memory first by KMD, instead of malloc first.
By default prefer not caching allocations on MTL devices. This results
in allocations being handled with non-coherent pat index.
For integrated devices when caching is not preferred do not allow
direct memory access in CPU domain. For map/unmap operations create
a dedicated memory allocation for CPU access, instead of accessing it
directly, reusing the same logic as when mapping/unmapping local memory.
