aux/tc: use renderpass tracking to optimize texture_subdata calls

Browse Source 
if it's known that a renderpass is active and the driver wants to do
renderpass optimizing, help out by not forcing a sync and instead doing
what the driver would do: create a staging buffer and copy it to the
image

this requires that the driver already handles buffer -> image copies
with resource_copy_region
