Convert libdrmframework and drmserver to Android.bp
See build/soong/README.md for more information. Also moves a few headers into the same library as their implementation, and fixes a few includes to go through the global frameworks/av/include path instead of manually adding frameworks/av/include/drm. Test: m -j checkbuild Change-Id: I0c2d2f2262e7ed78d80a0d44795705c64b797ff0
