[mlir][tosa] Disallow invalid datatype combinations in the validation pass

This commit checks if the operands/results of an operator can be found
in the profile compliance mapping, if it isn't the operator is considered
invalid. As a result, operator datatype combinations that are not listed
under the "Supported Data Types" of the TOSA specification are disallowed
and the validation pass results in failure.
