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.

- this method allocates System Memory
- argument is not needed - ExternalHeap is selected inside this function
- remove unneeded ults
- allocate memory in Device Pool for external heap allocation in

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

Create new file:
`os_handle.h` which contains OS specific Handle type.
Add `shared/source/os_interface/<windows/linux>`
include directory to level_zero.

- program surface states for redescribed images correctly. Image copy
to/from memory are using redescribed surface states,
- refactor state base address programming - program address and size
together, set max size at the beginning due to lack of Enable flag
- set GpuBase in WddmAllocation when external heap is used
- return max ssh required size from kernelInfo or based on stateful args

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.

The previous name "pageSize2Mb" defined in
shared/source/helpers/constant.h is inconsistent to other variable,
i.e. pageSize64k.
Furthermore, it's a bit misleading because the page size is defined in
Megabytes (MB), not in Megabits (Mb).

With direct submission disabled this resulted in waitTimeout long enough
that kmdWait fallback was rarely used.
This caused more CPU spin time.
