mesa: Support building without opengl

mesa can build certain things without opengl: most importantly vulkan
drivers.

Add comments on the dependencies between the packageconfigs. Also add
a few dependencies to packageconfigs. Modify default packageconfig to
do the reasonable thing based on distro features.

Add a backported patch to fix the build with --disable-opengl. Fix
do_install_append() so it works even if dri drivers are not built.
