Add the PowerVR SDK as a git submodule
The primary purpose of doing this is to have all the PowerVR SDK
examples in one place and remain up-to-date. This change also lets us
simplify a bit of our CMakeLists.txt as we only need to use
add_subdirectory to build everything we need.
The PowerVR SDK examples are built by explicitly enabling
SWIFTSHADER_BUILD_PVR_EXAMPLES (either through a cmake gui, or
-DSWIFTSHADER_BUILD_PVR_EXAMPLES=ON on the command line). You must also specify
a window system for the examples to use with something like
"-DPVR_WINDOW_SYSTEM=X11".
Several cmake option flags were renamed to start with "SWIFTSHADER_" to avoid
name collisions with subdirectories.
