Add build support in Soong for some run-tests exercising VarHandles.

Add build support for ART run-tests tests in Soong, which have custom
build scripts enabling support for Java variable handles. Ignore these
build script, as they are just used to enable build support for Java
variable handles, which are supported by default in Soong.

Note: We may later reconsider using different API levels when building
ART run-tests with Soong for use with TradeFed (as does the
`art/test/etc/default-build` script).
