feature: add new environment variables for compiler cache on Windows

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.
