Split the translation part as a separate PR and merged #150696
This PR now consists of serialization and integration tests. 
Addressed all comments.
Some notable changes made:
- Refactored code and moved parts independent of target triple into `SerializeGPUModuleBase`. And subclass  `SpirSerializer` provides custom `init` and `moduleToObject` function.
- Added `compileToBinary` that used `ocloc` an offline compiler for SPIR-V to Xe native binary. 
- Integration tests are now using new level zero runtime wrapper.

@fabianmcg @Jianhui-Li @kurapov-peter @adam-smnk @adam-smnk Can you take another look at the PR?
