Move LoadLibraryAndPrintError helpers to common gl_implementation.h/.cc

Move LoadLibraryAndPrintError helpers to common gl_implementation.h/.cc

These functions are implemented in gl_implementation_osmesa.cc
but used in gl_implementation_x11.cc and gl_implementation_android.cc.

If LoadLibraryAndPrintError fails the log message starts with
gl_implementation_osmesa.cc which is confusing.
