Minor Optimisation: Terminate early if we've passed the insertion point for tRetainedKeyframes

Feature Request T54106: When scaling keyframes, merge (by-averaging) selected keys
that end up on the same frame

Currently, when scaling keyframes in the Dopesheet, if multiple
selected keyframes end up on the same frame post-scaling, they
would not get removed by the "Automerge" setting that normally
removes duplicates on the same frame.

This commit changes the behaviour so that when multiple selected
keyframes end up on the same frame, instead of keeping all these
around on the same frame (e.g. resulting in a column of keyframes
on different values), we will instead merge them into a single
keyframe (by averaging the values). This should result in a
smoother F-Curve with fewer "stair-steps" that need to be carefully
cleaned out afterwards.

bezt_add_to_cfra_elem() - Use same keyframe equality test as in other places

This shouldn't affect anything currently, as this function doesn't appear
to get used anywhere.

Fix T54065: NLA-Strip Control Curves would get disabled when name-based-filtering is enabled

This bug took a while to track down. In the test file with this report,
the Nla-Strip Control Curve for strip time would get disabled if you
changed the NLA Editor to a second Graph Editor instance.

It turns out that because this second Graph Editor would have the
"filter fcurves by name" option enabled, this would trigger a lookup
of the referenced property's name (in order to test whether it matched
the filtering criteria). However, since that filtering code was written
before the introduction of these curves, it still assumed that the names
for these Control Curves should be handled the same as for standard FCurves.
Unfortunately, that doesn't work, as the property lookups fail if the standard
method is used - when the lookups fail, the F-Curves get tagged as being
invalid/disabled (and need to be reset using the "Revive Disabled FCurves"
operator).

Note: The changes in this patch look complicated, as I've had to shuffle
a bit of code around so that the name-filtering check can have access to
the additional info it needs. In the process, I've also removed the earlier
(hacky) approach where the control curves were getting added to a temp
buffer to get changed from normal FCurves to special ANIMTYPE_NLACURVES.

Fix more missing ID remapping in animation editor callbacks

Applying the same fixes as introduced in 98d797b67c07e85889768bf8ecde292e9e6f70e9
this time, for the Graph and NLA editors

Depsgraph: Fix fake dependency cycle with chained IK solvers with tip excluded

Not sure why we need a relation from solver to a tip local transform, this
will be handled via parent relation.

Fixes remaining dependency cycles reported in T54083.

VSE: skip non image/movie w/ proxy dir storage

This would use uninitialized filename variable,
looked into supporting this however generating proxies currently only
works for movies.

Depsgraph: Fix dependency when constraint influence drives some other constraint

It is not possible to address transform at particular position of constraint
stack, and when constraint is being addressed is usually from driver variable.

This fixes some of dependency cycles reported in T54083.
