    st/mesa: implement PBO downloads for ReadPixels

    v2: require PIPE_CAP_SAMPLER_VIEW_TARGET; technically only needed for s=
ome
of
        the texture targets, but all hardware that has shader images should
also
        have this cap.

I can provoke an oom on xorg as attached by displaying a couple of 1920 xwds
with display from ImageMagick and flipping between then, plus some middle m=
ouse
clicking (which magnifys a section and gives info on the pixel clicked).

Oom is not instant - may take a couple of minutes clicking/flipping.

Polling free when doing this doesn't indicate any issue until it triggers so
it's not slowly leaking, but goes quickly at some point filling swap then o=
om.
