Rewrite tests that fail when usm_shared_allocations not supported. (#12636)
Nearly 40 E2E tests use malloc_shared and do not expect an exception to be thrown in case of failure which is not what the spec says, namely, malloc_shared should throw when the usm_shared_allocations aspect is not supported by the device. At the moment malloc_shared simply returns nullptr, however, once the implementation of malloc_shared is changed to throw an exception these tests will produce failures. This PR is the first of a series of PR's to rewrite these tests so that they don't fail once malloc_shared is changed to conform to the spec. These changes will only affect devices that do not support the relevant aspect. This is done either: - by having llvm-lit require that the aspect is supported for tests that rely heavily on malloc_shared, - by disabling, through if statements, sections of code that use malloc_shared for tests that use it sparsely, - by completely rewriting the malloc_shared code with equivalent buffer/accessor code that is guaranteed to work on all platforms. The latter approach is taken on tests that do not have the purpose of testing malloc_shared but simply use it to allocate memory for the test. These changes aim to eliminate test failures while maintaining test coverage. Subsequent PR's will omit this description and refer to this PR instead.
