[NATIVECPU] Empty implementation for command buffer fill

[PietroGhg]

Adds empty implementations for urCommandBufferAppendMemBufferFillExp and urCommandBufferAppendUSMFillExp on Native CPU.
intel/llvm PR: intel/llvm#12379

[EwanC]

There's another couple of command-buffer entry-points added recently that we missed from native-cpu #937

• urCommandBufferAppendUSMPrefetchExp
• urCommandBufferAppendUSMAdviseExp.

Not sure if you want to include those here or a new PR (happy for you to include them here)

Hey Pietro would you mind removing the die calls and just leave these entry points as return UR_RESULT_ERROR_UNSUPPORTED_FEATURE? We're removing die/abort (#1127) and handling it in DPC++ (intel/llvm#12361). Cheers!
