Retry: Enable mainline prebuilts on tm-dev branch.
Except for santizer and framework Java coverage tests as they require
specialized prebuilts built from a matching configuration and we do not
provide them.
And products that use dex2oat(d)s as they are not available as a
prebuilt.
And products that cross compile to arm64 and linux_bionic on the host
as prebuilts for that are not available.
And atv/tv products as they break when building against prebuilts.
