DO NOT MERGE ANYWHERE Enable shader cache for applications that shared UID with multiple packages

Browse Source 
from AOSP: https://android-review.googlesource.com/#/c/209490/

Frameworks supported a mature mechanism for shader cache per each package already,
but as a special case such as Settings APP, if there are several packages in this
application which means that multiple packages shared the same SharedUserID with it,
it won't initialize the graphics disk caches, thereby APP like Settings have to
rebuild and relink shader every time during launch, which cause a bad launching
performance, so here to enable the GFX and RS cache initialization for multiple
shared packages case too.
