drm/amd/display: Add DC build_id to determine build type
[why]
Sometimes there are indications that the incorrect driver is being
loaded in automated tests. This change adds the ability for builds to
be tagged with a string, and picked up by the test infrastructure.
[how]
dc.c will allocate const for build id, which is init-ed with default
value, indicating production build. For test builds, build server will
find/replace this value. The test machine will then verify this value.
It seems DC_BUILD_ID is used by the build server, so maybe we should keep it.
