drm/amd/display: move stutter quirk to quirks file

Browse source

[WHAT]
dm_should_disable_stutter() and its amdgpu_stutter_quirk PCI match
table are self-contained quirk logic. Move them out of amdgpu_dm.c
into amdgpu_dm_quirks.c alongside the existing DMI quirk handling.

The helper is called from amdgpu_dm_init(), so it becomes a plain
exported function instead of STATIC_IFN_KUNIT, and its declaration
moves from the KUnit-only block to a regular prototype in amdgpu_dm.h.
Relocate its KUnit tests from the amdgpu_dm suite to the
amdgpu_dm_quirks suite. No functional change.
