[BINDLESS][E2E] Split image_get_info into three tests

[JackAKirk]

image_get_info.cpp previously comprised three types of tests which have been split into separate test files

• testing queries of a oneapi::experimental::image_mem instance (image_get_info.cpp)
• testing device queries for image requirements (either max image dimensions or pitch alignment) (image_reqs_get_info.cpp)
• testing device queries for bindless images aspects (bindless_aspects.cpp)

This PR splits up these tests which is useful for diagnosing problems on different backends:

• image_get_info.cpp is currently only unsupported on the HIP backend (Known issue)
• image_reqs_get_info.cpp is currently only unsupported on the L0 backend [BINDLESS][L0] Fix image requirement queries on L0 in driver/UR #17663
• bindless_aspects.cpp has been fixed on L0 backend so it now passes on all backends, by only querying mipmap_max_anisotropy if aspect::ext_oneapi_mipmap_anisotropy returns true
