  [MLIR][OpenMP] DeclareTargetInterface and DeclareTargetAttr cleanup

The changes introduced by this patch are intended to avoid triggering
multiple by name lookups to the "omp.declare_target" attribute every
time any data from the `DeclareTargetInterface` is queried, remove the
need for keeping multiple default values for the same data, clean up
the assembly format and generally improve the usage of the interface.

List of changes:
- `DeclareTargetInterface` only provides `setDeclareTarget` and
  `getDeclareTarget` methods to handle the "omp.declare_target"
  attribute, maintaining a single canonical way of accessing it.
- `DeclareTargetAttr` provides direct access to the capture clause and
  device type enums, rather than wrapping them into an `Attribute`.
  These are now mandatory as well. Both changes together make accessing
  them more straightforward and simplify the attribute representation.
