Two years ago, `operand_segment_sizes` and `result_segment_sizes` were
renamed to `operandSegmentSizes` and `resultSegmentSizes` (check related
commits, e.g.
363b655920).
However, the op verifiers in IRDL loading phase is still using old
attributes like `operand_segment_sizes` and `result_segment_sizes`,
which causes some conflict, e.g. it is not compatible with the OpView
builder in MLIR python bindings (which generates camelCase segment
attributes).
This PR is to support to use camelCase segment size attributes in IRDL
verifier. Note that support of `operand_segment_sizes` and
`result_segment_sizes` is dropped.
I found this issue since I'm working on a new IRDL wrapper in the MLIR
python bindings.
