  [MLIR][Remark] Import LLVM optimization remarks into the remark engine (#222300)

Collect LLVM side of remarks with MLIR's remark infra.

LLVM passes emit their own [optimization
remarks](https://llvm.org/docs/Remarks.html) and MLIR has own. This PR
bridges MLIR and LLVM remarks.

`ModuleToObject` installs a `remark::LLVMToMLIRDiagnosticHandler` on the
`llvm::LLVMContext` it compiles with, which imports these remarks into
the remark engine: the category is the LLVM pass name prefixed with
`llvm-`, the LLVM remark name becomes the name, the message is stored
under the `Remark` argument and the structured LLVM arguments are copied
as metrics. The remark filters therefore select LLVM remarks by pass
name, and `llvm-.*` selects all of them.
