[OE-core] [PATCH][V2 2/4] mesa-gl: add GL-only Mesa recipe

[Ross Burton]

Some machines have hardware-specific GL drivers that do EGL and GLES (many ARM
boards).  Others have their own EGL/GLES drivers and provide a Mesa DRI driver
(EMGD).  Previously adding Mesa, for software GL/GLX rendering in the first case
and hardware GLX in the second, involved bbappends and changing Mesa to be
machine-specific.

By adding a just-GL Mesa the machine definition can combine it with the hardware
drivers cleanly.
