[uArch][XeGPU] Add XeGPU uArch definition. (#153706)
The uArch infrastructure provides:
- A set data structures to represent, uArch and it's necessary
components (e.g., instructions, register-files, caches).
- A set of utility interfaces that are common to a family of ops (e.g.,
mma ops, 2DBlockIO ops). The implementation of these interfaces are
provided by the specific instructions. Each family of ops provides these
5 common APIs. However, some family of ops may have more utility APIs.
The common 5 APIs are:
- getSupportedShapes
- getSupportedTypes
- checkSupportedShapesAndTypes
- checkSupportedTypes
- validate
Add support for PVC and BMG architectures.
Add support for DPAS instruction.
