package/mesa3d: add Gallium VA-API support

Browse Source 
Since commit 361bfbc70b (package/mesa3d: disable libva support),
VA-API has been unconditionally disabled in mesa3d due to a circular
dependency between mesa3d, libva and libgl.

The circular dependency only occurs when mesa3d is the libgl provider,
i.e. when GLX is enabled without libglvnd. In that case:
  mesa3d -> libva -> libgl -> mesa3d

Re-enable VA-API support as a new BR2_PACKAGE_MESA3D_GALLIUM_VA option,
guarded by a dependency that prevents the circular case. This allows
hardware video acceleration on AMD, Intel and other GPUs with Gallium
drivers.
