drm/amd/display: Relax DML frame limit with UBSAN
[WHY]
UBSAN instrumentation adds checks and handler calls and increases
stack usage in the large DML calculation functions, similar to
KASAN and KCSAN. With UBSAN enabled these files exceed the default
-Wframe-larger-than limit and fail to build when -Werror is in effect.
Reproduced with LLVM (make LLVM=1, clang 19.1.1), CONFIG_UBSAN=y,
CONFIG_GCOV_PROFILE_ALL=y and CONFIG_DRM_AMDGPU_WERROR=y on x86_64.
[HOW]
Include CONFIG_UBSAN in the sanitizer check that selects the
higher per-file frame warning limit in the dml and dml2_0
Makefiles.
