read_depth_offset: new test to check depth offset calculation
We have tests to validate depth offsets in general, but these
apply to the default depth buffer (usually 24 bit fixed point).
This test checks the details of the depth offset calculation
by using NV_read_pixel to read back the written values, and
verifies that e.g. the minimum resolvable difference used for
floating point buffers matches the spec. This revealed a bug
on panfrost.
