Add #ifdefs to separate NaCl and non-NaCl PPAPI Proxy code.

Add #ifdefs to separate NaCl and non-NaCl PPAPI Proxy code.
This CL moves non-NaCl interface proxies like Flash, and also
temporarily moves unported interfaces such as Graphics3D.

I tried to keep the number of #ifdef-#endif blocks to a minimum by moving
things. If that seems too choppy I can maintain the original ordering and add
more #ifdefs.

This gets the build to the link stage with only IPC channel stuff missing.

This no longer compiles. We don't seem to need it.

I aggressively removed stuff we don't need for the proof-of-concept.
