[mlir][acc] Add support for data clause modifiers (#144806)

The OpenACC data clause operations have been updated to support the
OpenACC 3.4 data clause modifiers. This includes ensuring verifiers
check that only supported ones are used on relevant operations.

In order to support a seamless update from encoding the modifiers in the
data clause to this attribute, the following considerations were made:
- Ensure that modifier builders which do not take modifier are still
available.
- All data clause enum values are left in place until a complete
transition is made to the new modifiers.
