Move BufferHub-based IGBP into libgui
Currently the BufferHub based IGBP implementation lives inside
frameworks/libs/vr and libbufferhubqueue is depending on libgui. This CL
reverses the dependency and paves the way of future integration of
BufferHub into libgui.
Mirrors changes to make this work:
1/ Fix shared lib dependency of libpdx
2/ Allow implicit template instantiation in libgui
3/ Mute clang warnings caused by libpdx
Bug: 72051005
Bug: 70046255
Test: libgui-test, buffer_hub_queue_producer-test, dvr_api-test
