glx/egl "multibuffers" denotes if server side support DRI3
multi plane and modifiers which is version >= 1.2. But now
it returns true just when DRI3 version >= 1.
This causes problem when xserver with amdgpu DDX which only
support DRI3 1.0, so "multibuffers" gets set unexpectedly,
and client send DRI3 >= 1.2 request to server which gets
unimplemented error.

this existed for historical reasons, but realistically now it should
be possible to build mesa with dri3 always enabled. additionally,
this check was often used as a substitute for having drm functionality,
which is sort of similar but also not really a direct match
this simplifies a bunch of conditionals and prevents users from footgunnning
themselves into orbit
