Some host-compilers may create lambdas with captures that do not match the ones used when extracting kernel descriptors. The compiler does not currently have a stable way of handling these cases, so instead this PR adds a static assertion that the sizes match with a message informing about the limitation.

Ideally we should check that sizeof(long long) is 8, if sizeof(long) != 8.

I agree, but this mimics the decision made by SemaSYCL when generating the specialization, so it should be fine for our testing.

Nice, perhaps this will also fix one of internal trackers reporting problems with undefined int8_t type slipped into integration-header file.
