CLOG: Add getter to know if output supports coloring

GPU: Use CLOG to for debug output

This removes the escape color control caracters when the output
does not supports it (i.e: file output, windows cmd).

GPU: Debug: Trim shader stats from output log

We don't make use of it anyway.

Fix T81969 VSE: Wrong UI colorspace after scene strip update

This regression was caused by rB57de5686048f which disabled srgb
transform after the python callback.

The right thing to do is to only rebind the framebuffer once to
reset the no-srgb override.

Fix T73793 Walk navigation crosshair gets hidden behind objects

This was reintroduced by the wide line emulation workaround.

Fix T81942 EEVEE: Reflection Plane glitch with low clip distances

This was happening because the raytrace was not even being performed
due to the tracing line being too small after frustum clipping.

DRW: Fix custom engine not being BGL safe

This was caused by unprotected drawing callbacks.
As of 2.91, we require that all python callbacks used for
drawing needs to be safeguarded by `GPU_bgl_end()` to end the
state tracking override.
