[SYCL][E2E] Enable passing UNSUPPORTED:gpu tests (#15391)

This commit enables a selection of tests with UNSUPPORTED:gpu that seems
to have been fixed since their disablement.

Additionally, it restricts expected failure of image_array to just
Gen12, with tracker #15398.

-// E2E tests for annotated USM allocation functions with alignment arguments

-// tests expect non-templated aligned_alloc_xxx functions to return nullptr,
-// e.g. when the alignment argument is not a power of 2, while they fail to do
-// so when run on gpu. This maybe because the gpu runtime has different
-// behavior. Therefore, GPU is unsupported until issue #12638 gets resolved.
