FFmpeg: Adjust default proxy settings

GOP size and quality are adjusted for h264 codec.

These new values are based on result of benchmark on 9 random files:
https://docs.google.com/spreadsheets/d/1nOyUGjoVWUyhQ2y2lAd8VtFfyaY1wQNGj1krCCNbk7Y/edit?usp=sharing

Reducing quality to 50 reduces proxy filesize by about 2x on average
and has no significant impact on decoding performance.

Increasing GOP size from 2 to 10 also reduces proxy filesize 2x-3x
while scrubbing is only about 8% slower. It is still around 100FPS
with 1920x1080 media.
This is unfortunately about 50% slower than MJPEG, but this can be
improved with `fastdecode` tune applied to libx264 encoder

Quite surprisingly h264 codec presets had little influence on proxy
building performance as well as proxy filesize. So far it looks that
FFmpeg does initialize encoder in different way then Blender.
This applies mot only for presets but for tune and profile libx264
setting.
Once this issue is resolved, performance of proxies may be optimized
further.

Fix T87479: GPencil SVG export outside of camera

When trying to export a GPencil object to SVG from outside the camera
view, the expoted file would contain invalid data. This was because the
calculation of the bounding box did not have any objects to
iterate over.

The fix makes sure we create the object list before trying to calculate
the bounding box.

Cycles: Rework passess data access

The idea is to move pass access away from RenderBuffers to a place
where list of passes is known. Most obvious choice is the Session.
A bit of trickery comes from the fact that in theory PathTrace might
have multiple RenderBuffers (in the case of multi-device render).
So the pass access happens via session into the PathTrace.

There is a helper class which pre-calculates various offsets which
can be re-used by updates form multiple devices.

Fix (unreported) compositor resolution propagation broken by some nodes

Some operations may use no preferredResolution ({0, 0}) when calling determineResolution on inputs to check if they have resolution on their own. See MixOperation or MathOperation determineResolution implementation. In such cases {0, 0} resolution ends up being set when an input doesn't have own resolution, breaking propagation of the original preferredResolution. They don't mean to set it as resolution, it's just a check.

This patch only allows to set valid resolutions (>0). When it's 0 it may be understood as "No preferred or determined resolution" so it should not be set to give output operations another chance of finding a proper resolution by calling determineResolution again with a different preferredResolution.
