Introduce a Soong config variable to flip to ART Module sources when

prebuilts are preferred by default.

It enables the apex/sdk/module_exports modules and toggles off the
prefer flags on the ART Module prebuilts when the ART-specific products
are used, typically on master-art.

Also add new generic architecture products for use in
art/build/build-art-module.sh to build the ART Module prebuilts.

Test: m TARGET_PRODUCT=art_module_{arm,arm64,x86,x86_64} nothing
