[Buildroot] [git commit] package/mesa3d: add config option for DRI3 support

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=8892b25edabe7ce168869a3ad25bd9693059cebe
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add config option for DRI3 support and use it instead
of DRI3 enable/disable logic in *.mk file.

Move the libxshmfence dependency to the DRI3 option, cfr. the following
in meson.build:

    if with_dri3
      ...
      dep_xshmfence = dependency('xshmfence', version : '>= 1.1')
    endif

Also select DRI3 in the Vulkan Intel driver.
