Remove deprecation warning for OpenMPDeclarativeAllocate

As per the spec for OpenMP 5.2, it is only when the allocate
directive is followed by an allocate statement that has been
deprecated. This commit removes the deprecation for the declarative
version of `allocate`, and updates the appropriate tests to
accomodate this.
