  [mlir][tosa] Add row_gather_block_scaled op (#192272)

Add `tosa.row_gather_block_scaled` to the MLIR TOSA dialect, aligned
with the current TOSA 1.1 draft spec and the implementation in
`tosa-tools`.

  This includes:
  - op definition
  - verifier and shape inference support
  - validation / profile compliance wiring
  - availability and extension handling
- lit tests for parsing, verification, shape inference, and version /
extension gating

  The op supports both spec-defined forms:
  - non-block-scaled: 1 input value tensor, `BLOCK_SIZE_1`, 1 output
- block-scaled: data + scale tensor list, non-`BLOCK_SIZE_1`, 2 outputs

Op-specific level checks for ROW_GATHER_BLOCK_SCALED have been deferred
while the TOSA 1.1 draft is still evolving.
