emulator/opengl: Remove out-of-process handling code.

This removes the last pieces of shared/OpenglOsUtils
which were never used since the code in render_api.cpp always
used thread-based rendering, instead of process-based one.

This feature could be re-implemented in the future, if really
desirable.
