[mlir] Make `TypedStrAttr` actually enforce the string type. (#124770)
The tablgen definition `TypedStrAttr` is an attribute constraints that
is meant to restrict the type of a `StringAttr` to the type given as
parameter. However, the definition did not previously restrict the type;
any `StringAttr` was accepted. This PR makes the definition actually
enforce the type.
To test the constraints, the PR also changes the test op that was
previously used to test this constraint such that the enforced type is
`AnyInteger` instead of `AnyType`. The latter allowed any type, so not
enforcing that constraint had no observable effect. The PR then adds a
test case with a wrong type and ensures that diagnostics are produced.
