iris: Track per-stage bind history, reduce work accordingly
We now track per-stage bind history for constant and shader buffers,
shader images, and sampler views by adding an extra res->bind_stages
field to go with res->bind_history.
This lets us flag IRIS_DIRTY_CONSTANTS for only the specific stages
involved, and also skip some CPU overhead in iris_rebind_buffer.
Cuts 4% of 3DSTATE_CONSTANT_XS packets in a Shadow of Mordor trace
on Icelake.
