drm_hwcomposer: Add support for P+ environments

Originally-by: Alistair Strachan <astrachan@google.com>

With Android P, the GraphicBufferMapper ImportBuffer interface
has changed, which breaks the current drm_hwcomposer master
branch:
https://android.googlesource.com/platform/frameworks/native/+/dbbe33b95336efa74e8bb4ebcf6cba50919aa247

Alistair has updated the AOSP/master branch of drm_hwcomposer to
make it build:
https://android.googlesource.com/platform/external/drm_hwcomposer/+/4f73630dcdab6604a3f4b3e7d59068633d923745%5E2..4f73630dcdab6604a3f4b3e7d59068633d923745/

But since we need to keep older users working, so I've forward
ported and conditionalized the code so both new and old users
can properly build.
