Use prebuilts of the ART Module by default in SC branches.
This means prebuilts located in
/vendor/unbundled_google/modules/ArtGooglePrebuilt and
/prebuilts/module_sdk/art are used instead of sources in /art,
/libcore, and /libnativehelper.
Sanitizer and coverage builds builds are excluded, as are builds using
the products art_module_*, armv8, arm_krait, and others in
device/generic/art.
To keep using ART and libcore sources in local builds, set
SOONG_CONFIG_art_module_source_build=true. See art/build/README.md for
further info.
Cherry-picked from http://ag/15234812.
Merged-in set to https://r.android.com/1801147 to avoid merging into
master and *-plus-aosp branches, where we want to enable prebuilts
separately.
