I'm fine with adding more CAPIs about `DynamicDialect` (I'm who added the initial C APIs about `DynamicDialect` previously), just to clarify some points in PR description, before reviewing.

This is not true. You can create and register a DynamicDialect into MLIR context via the IRDL dialect. This is how Python-defined dialects in MLIR Python bindings works. You can check [`mlir.dialects.ext`](https://github.com/llvm/llvm-project/blob/main/mlir/python/mlir/dialects/ext.py) module and [its test case](https://github.com/llvm/llvm-project/blob/main/mlir/test/python/dialects/ext.py) about this.
