Fix T67459: Dope Editor, muting channels with shortcut doesn't work

Fix T67089: Solve camera motion generates "Solve error: nan"

The code was missing some checks for whether keyframe selection
went successfully and whether reconstruction has been successfully
initialized.

The interface still gives quite generic message, with the details
printed to the console. This can be addressed separately.

Tracking: Give more reasonable error message directly in the interface

Before this the message could be too generic which was simply saying
that console is to be checked. This isn't very useful in cases when
we know that reconstruction is failed because of lack of good keyframes
or failure of initial reconstruction if there is no enough parallax
on the selected keyframes.

Fix compositor ignoring mask parenting

There are two aspects to the problem:

- Dependency graph update for compositor preview was missing
updates flush.

Apparently, update for new frame style of update will take
care of flushing, but not the update tagged style of update.

This goes to a legacy dependency graph and is to be changed
at some point, but not so close to the release.

- Movie clips were missing from the compositor dependency graph.

This fixes part of T66519.

Fix T66812: Particles + Build Modifier = Crash

Particles can not be used with a destructive modifiers, so we can not
maker such configuration fully reliable.

Not sure this specific setup ever worked in 2.7x, maybe DM index was
somehow reset somewhere in particle system in older Blender version,
or maybe all of Blender version were crashing.

Anyway, seems to be very easy to avoid obvious index past the array
boundary in the mapping,
