This patch adds support for timing GPU compositor executions. This was
previously not possible since there was no mechanism to measure GPU
calls, which is still the case. However, since 2cf8b5c4e1, we now flush
GPU calls immediately for interactive editing, so we can now measure the
GPU evaluation on the host, which is not a very accurate method, but it
is better than having no timing information. Therefore, timing is only
implemented for interactive editing.
This is different from the CPU implementation in that it measures the
total evaluation time, including any preprocessing of the inputs like
implicit type conversion as well as things like previews.
The profiling implementation was moved to the realtime compositor since
the compositor module is optional.
