etnaviv: resolve tile status when flushing resource
When passing render buffers from EGL clients to a wayland compositor,
the resource tile status must be resolved because otherwise the tile
status is lost in the transfer and cleared parts of the buffer will
contain old contents.
The same applies when sampling directly from a renderable resource.
lst: Add seqno tracking, to skip flush when not needed.
Fixes: aadcb5e94b35 ("etnaviv: enable TS, but disable autodisable")
