[MLIR][Transform] expose transform.debug extension in Python (#145550)

Removes the Debug... prefix on the ops in tablegen, in line with pretty
much all other Transform-dialect extension ops. This means that the ops
in Python look like
`debug.EmitParamAsRemarkOp`/`debug.emit_param_as_remark` instead of
`debug.DebugEmitParamAsRemarkOp`/`debug.debug_emit_param_as_remark`.
