Update BIND_SHARED_ISOLATED_PROCESS documentation.

     * will cause the isolated service to be co-located in the same shared isolated process.

     *

     * Note that the shared isolated process is scoped to the calling app; once created, only

     * the calling app can bind additional isolated services into the shared process.

     * the calling app can bind additional isolated services into the shared process. However,

     * the services themselves can come from different APKs and therefore different vendors.

     *

     * Only services that set the {@link android.R.attr#allowSharedIsolatedProcess} attribute

     * to {@code true} are allowed to be bound into a shared isolated process.
