[SYCL][NFC] Employ the is_same_v helper in SYCL library

[AGindinson]

Similarly to [b469f03], refactor the usages of the
is_same type trait to reduce code verbosity. This particular
trait was chosen because of its popularity, and will probably
be the last in this refactoring series.

clang-format seems to be firing a false alarm: 1 of the chunks is irrelevant to my changes. Dear reviewers, I would appreciate some advice on how to proceed here.

The MSVC build failure is somewhat resembling this SO bug description.

What clang-format version do you use locally? I think we should try using new version in CI. I think we should clang-format-9 today and it's quite old, so this issue might be already fixed in later versions.

I'm basically using a self-built one, which is around version 12. How would we go about updating the one used by CI?

I suggest using clang-format version used by CI system to avoid misalignments.

Looks good.

Changes in the ESIMD RT library look good.

Closing after the shift to C++14. Further refactoring should just use the std:: variant of type traits.
