feature: Add Initial Support for Get Vector Width Properties

Browse Source 
- Added support for L0 to query Vector Width Properties which allows for
querying all the supported vector widths and their prefferred and
native vector widths per data type.
- Updated shared code to support querying the same values thru
getPreferredVectorWidth* and getNativeVectorWidth* helper functions
for OpenCL and Level Zero.
- Initial support for reporting base values for the vector
widths with future support for reporting different values per platform and
based on the SIMD/SIMT size used.
