[SYCL][UR][L0 v2] Implement missing bindless images functionality (#19808)

Implement urBindlessImagesSignalExternalSemaphoreExp and
urBindlessImagesWaitExternalSemaphoreExp. The implementation is the same
as in the legace adapter, except that we don't to a fallback in case old
loader is used (v2 is supposed to be used with a new enough L0 loader
version).
