[SYCL][LIT] Disable tests that fail with libc++ (#19618)

sarnex · web-flow · commit 8d1e141dd6c3 · 2025-07-29T15:21:51.000Z
These tests fail when the compiler is built with libc++.
All have Github issues tracking them.

Some of the tests are gtest and not lit so I had to disable those in
CMake. Using defines isn't safe because the problem is the compiler
being compiled with libc++, not necessarily it currently being used to
compile the tests.
