JIT: Skip test validating release debug info mappings (#112942)

The test of time has shown that this test just ends up being another
place to modify, and it has never caught anything useful. At the same
time it is currently disabling several JIT optimizations to pass, but
those optimizations can only  be disabled with checked JIT builds, so the
test ends up failing in release.

Fix #104451
