etnaviv: fix tile status interaction with write mappings

Browse source 
This fixes a longstanding bug in the interaction between TS and a write
mapping. The write does not update TS regardless of the way the update
is done. Update via etna_copy_resource would just set the target ts_valid
to false without actually writing back any dirty TS to the resource.
Writes via the CPU would update the resource, but keep ts_valid at true
even if the tile status may now not match the actually written tiles of
the resource anymore.

Fix this by writing back a dirty TS to the target resource if needed
before updating the level with the write data. Always invalidate TS,
even when the update is done by the CPU.
