19db802e7b [mlir] make implementations of translation to LLVM IR interfaces private
There is no need for the interface implementations to be exposed, opaque
registration functions are sufficient for all users, similarly to passes.

ce8f10d6cb [mlir] Simplify ModuleTranslation for LLVM IR
A series of preceding patches changed the mechanism for translating MLIR to
LLVM IR to use dialect interface with delayed registration. It is no longer
necessary for specific dialects to derive from ModuleTranslation. Remove all
virtual methods from ModuleTranslation and factor out the entry point to be a
free function.

Also perform some cleanups in ModuleTranslation internals.

Depends On D96774

176379e0c8 [mlir] Use the interface-based translation for LLVM "intrinsic" dialects
Port the translation of five dialects that define LLVM IR intrinsics
(LLVMAVX512, LLVMArmNeon, LLVMArmSVE, NVVM, ROCDL) to the new dialect
interface-based mechanism. This allows us to remove individual translations
that were created for each of these dialects and just use one common
MLIR-to-LLVM-IR translation that potentially supports all dialects instead,
based on what is registered and including any combination of translatable
dialects. This removal was one of the main goals of the refactoring.

To support the addition of GPU-related metadata, the translation interface is
extended with the `amendOperation` function that allows the interface
implementation to post-process any translated operation with dialect attributes
from the dialect for which the interface is implemented regardless of the
operation's dialect. This is currently applied to "kernel" functions, but can
be used to construct other metadata in dialect-specific ways without
necessarily affecting operations.

Depends On D96591, D96504

72c65b698e [mlir] Move TestDialect and its passes to mlir::test namespace.
TestDialect has many operations and they all live in ::mlir namespace.
Sometimes it is not clear whether the ops used in the code for the test passes
belong to Standard or to Test dialects.

Also, with this change it is easier to understand what test passes registered
in mlir-opt are actually passes in mlir/test.

061fb8eb2d [mlir][gpu][mlir-cuda-runner] Refactor ConvertKernelFuncToCubin to be generic.
Make ConvertKernelFuncToCubin pass to be generic:

- Rename to ConvertKernelFuncToBlob.
- Allow specifying triple, target chip, target features.
- Initializing LLVM backend is supplied by a callback function.
- Lowering process from MLIR module to LLVM module is via another callback.
- Change mlir-cuda-runner to adopt the revised pass.
- Add new tests for lowering to ROCm HSA code object (HSACO).
- Tests for CUDA and ROCm are kept in separate directories.
