Revert "Add standalone ART gtests to `TEST_MAPPING` group `mainline-presubmit`."

This reverts commit 506b64c3b001dc32c59b8e63ce2e6d6cf4451fcb.

Reason for revert: Some standalone ART gtests are failing in presubmits
when built from sources where the Oat file version has been updated
-- compared to current prebuilt ART APEXes -- and run against such a
prebuilt ART APEX, that does not include that Oat version change.

Test: Rely on TreeHugger presubmits
