opengl: Fix pixelDataSize() ambiguity.

The GLESv1 encoder library was calling the pixelDataSize() function
definition from the GLESv2 encoder library, resulting in bugs, like
the inability to see the boot animation when -gpu on is used.

This fixes the issue by using namespaces to differentiate the
two implementations. Note that the auto-generated files have been
updated by re-running update-emugl-sources.sh as specified by
opengl/README after applying the following patches:
