Previous implementation skipped resolving the subDeviceId token, which
caused in returning the LinkedPartially status if token was present.
It could result in ZE_RESULT_ERROR_INVALID_MODULE_UNLINKED when kernel
was created and crashing an app.

In a scenario where fp64 emulation is both supported and enabled,
we want to include 2 additional extensions:
- cl_khr_fp64 to deviceExtensions
- __opencl_c_fp64 to openclCFeatures (OpenCL ver. 3.0)

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.

Current flow will be to have one synchronization point
config.file. Read remains unblocking, only write(caching)
operation will be blocking (lock on config.file)

This patch adds FP64 emulation support for ATS-M.
Introducing new environment variable - NEO_FP64_EMULATION - which provides
an option to allow the opt-in emulation of FP64.
When emulation is enabled, we pass -cl-fp64-gen-emu (ocl) /
-ze-fp64-gen-emu (L0) as an internal option to IGC.
