Fix Regex signature types

[blaginin]

Which issue does this PR close?

Closes #12664.

Rationale for this change

As pointed out in the original issue, REGEX_MATCH and REGEX_LIKE fail if the first argument is LargeUtf8 but the second (or third) argument is Utf8. We were performing as_generic_string_array::<i64> on &GenericStringArray<i32>, which caused the issue.

What changes are included in this PR?

Regex Match implementation in Apache Arrow requires the input and patterns to have the same type, and the flags to have the same type as well. I have reflected this change in the function signatures.

Are these changes tested?

Yes, by string_query.slt.part

Are there any user-facing changes?

No, only a bugfix.

Thanks for the review, @goldmedal! I've uncommented your tests and also added flags testing. Quite a cool string test setup, by the way! ;)
