tu: re-emit vertex buffer on MESA_VK_DYNAMIC_VI_BINDINGS_VALID dirty.
Previously cmd->state.vertex_buffers.size changing would not trigger
a re-emission of the state, leading to dEQP-VK.dynamic_state.*.line_width.*
failing on A7XX.
The tests only pass after !28206 (merged) is also applied, as there don't appear to be other tests in CTS that currently trigger the behaviour that also do not use wideLines.
