Add SurfaceInterceptor initial implementation

SurfaceInterceptor allows capturing streams of surface updates
that come into SurfaceFlinger. It captures the creation and
deletion of surfaces, changes to a surface like size or position,
buffer updates, and hw vsync updates (for a complete list of what
is captured see
/frameworks/native/cmds/surfacecapturereplay/proto/src/trace.proto)
SurfaceInterceptor uses a protocol buffer object to store each
trace. This allows for the produced trace to be either played back
into SurfaceFlinger or manually inspected.

To enable the interceptor: service call SurfaceFlinger 1020 i32 1
To disable the interceptor: service call SurfaceFlinger 1020 i32 0

Each trace file will be saved to /data/SurfaceTrace.dat
For SurfaceInterceptor to work SELinux must be set to permissive.
