[SYCL][E2E] Replace TEMPORARY_DISABLED by UNSUPPORTED (#15946)

To unify the mechanism to disable tests this patch replaces `REQUIRES:
TEMPORARY_DISABLED` by `UNSUPPORTED: true` to disable the test. Also
updating the tests using "TEMPORARY_DISABLED".

 If you add `UNSUPPORTED` without `UNSUPPORTED-TRACKER` or `UNSUPPORTED-INTENDED`
 directive, the `no-unsupported-without-tracker.cpp` test will fail, notifying
 you about that.
+
+To disable the test completely, you can use:
+```
+// USNUPPORTED: true
+```
+
+Note: please avoid using `REQUIRES: TEMPORARY_DISABLED` for this purpose, it's
+a non-standard mechanism. Use `UNSUPPORTED: true` instead, we track
+`UNSUPPORTED` tests using the mechanism described above. Otherwise the test
+risks remaining untraceable.
