Revert "[NFC][clang][test][asan] Make `instantiation-depth-default.cp…

…p` a valid test case under `asan` and `ubsan` configs (#75254)"

Disables the recursive template expansion test under ASan again. This
patch re-enabled this test with sanitizers, but it's started spuriously
failing with a stack overflow again on AArch64+ASan:
https://lab.llvm.org/buildbot/#/builders/239/builds/6363

This reverts commit c458f92.
