Subject: move the texture binding to a push descriptor

with a descriptor update template, even

yay

this also moves us to a minimum Vulkan version of 1.4, which we understand to be widely deployed. in theory, push descriptors and update templates were available via extensions in earlier versions, but it doesn't seem worth doing the work to switch out whether we use the extensions based on the version, so we don't.

Force-Push: yes
