  [MLIR][IRDL] Instantiate "." in IRDL-defined names as nested namespaces (#207035)

In PR #187911, it was revealed that the constraints on IRDL op names
placed by irdl-to-cpp were too restrictive.
This PR will address that by allowing "." in operation names to denote
nested namespaces, but not "$".

To discuss:
- ops like `wmma.f16.16x16x64.bf8_bf` cannot be registered as C++
identifiers cannot begin with a number. In discussions, we have opted to
prefix the generated namespaces with _.

Codex was used to generate the lit tests.

Close #187911.
