Disable most ART source modules when ART prebuilts are enabled.

After libdexfile_external was merged into libdexfile, libdexfile is an
APEX stub when prebuilts are enabled, and that cannot be used to build
libart and all the other internal modules that depend on it.

This CL:

- Changes art_defaults to disable native modules when building from
  prebuilts. Some other modules that depends on them, like the
  art-script sh_binary, also get disabled.
- Consolidates the makefile sections that are disabled when building
  from prebuilts so that only a small bit is still enabled then.
- Temporarily removes the prebuilt for libctstiagent and activates its
  source even when prebuilts are used, to work around sdk_version
  problem (b/187288515).
- Removes explicit "enabled: true" in a couple of places that would
  override the inherited flag that lets us disable them in builds from
  prebuilts.
- Makes some Soong defaults available to libcore.
