Mirza Halilčević 1fc49ff593 [MLIR][AMDGPU] Add OCP FP8 support for new hardware (#127728) ...

(Continuing from #106160)

This PR addresses remaining review comments from the original PR.

Original PR Description
---
Upcoming hardware (gfx12 and some future gfx9) will support the OCP
8-bit float formats for their matrix multiplication intrinsics and
conversion operations, retaining existing opcodes and compiler builtins.

This commit adds support for these types to the MLIR wrappers around
such operations, ensuring that the OCP types aren't used to generate
those builtins on hardware that doesn't expect that format and,
conversely, to ensure that the pre-OCP formats aren't used on new
hardware.
