[OE-core] [RFC][PATCH] mesa-gl: add GL-only Mesa recipe

[Kamble, Nitin A]

Hi Ross,
  This is a clever way to deal with unnecessary rebuilding of mesa we were seeing earlier. With this mesa-gl,
the mesa also need modification to remove gl from the default recipe.

Also looks like there is a need from community for mesa-gl-lib and mesa-gl-headers, as some
platforms need just the mesa-gl-headers and not the libs.

Nitin
