[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

-// so when run on gpu. This maybe because the gpu runtime has different
