UAF Control Rig: Refactor the control rig trait and evaluation task to be more modular so that the control rig evaluation task can be used outside of UAF in Sequencer animation mixer evaluation.

6fac5fb MovieSceneMixedControlRig
Sequencer Control Rig: Make control rig work through the anim mixer and be able to be mixed in any order with animations.
For now, this doesn't work underneath the 'anim mixer' track- this will be the next step. But this gets it working through the anim mixer code without creating a new custom anim instance. This effectively enables Control Rig in Sequencer to work with UAF.
A few notes:
* This follows the same pattern of creating a new 'mixed control rig system' that tags existing control rig entities (just the base rig entity) so that the original control rig system doesn't process certain things, in particular, that it doesn't create a new custom anim instance or do anything having to do with cached restore state for that anim instance. However unlike the skeletal animation system refactor, this does leave the initial control rig system to do most things, since most operations there happen on the ControlRig instance itself, which is the same in both cases.
* This is implemented in a new 'MovieSceneMixedControlRig' experimental plugin, due to the dependencies on the Control Rig plugin, the experimental UAF plugin, the experimental Anim Mixer plugin, and the experimental UAF Control Rig plugin. To test this, all of those plugins must be enabled in your project. It's been tested in AnimSandbox and the ContentExamples project.
* By default the control rig is still going through the old evaluation template workflow rather than its new ECS workflow. This change requires the change to the ECS workflow via setting ControlRig.UseLegacySequencerTemplate to false.
* There are still some open questions about how layered control rigs vs. regular control rigs should work with this. Currently both are allowed to be weighted and there is always a mix step therefore added, meaning from a mixer perspective there is no real difference between them, but perhaps we want there to be, e.g. perhaps Control Rigs should always overwrite the previous pose entirely.
* It was challenging to make this 100% backwards compatible with sequences having an animation and multiple control rig layers due to ordering issues, but some magic numbers have been used in the default priorities to apply for animation vs. control rig priorities that don't have anim mixers. Long-term the true backwards compatibility path will likely be to add these automatically to an anim mixer track in postload which should help with some of that since it'll just be about order rather than magic numbers.

Hierarchy Viewer:
Add a column on the widget row and cell widget rows that can be used to access the hierarchy interface the viewer is operating on

TEDS Visibility widget:
- FIx selection only operating on level editor selection set, it operates on the same set as the target row now
- Use hierarchy interfaces instead of hardcoded logic to use Outliner tree items, but keep the latter as a fallback for now

b4ecc2c UAFUncookedOnly
Scoped compile job changes:

> Renamed FScopedCompileJob to FCompilationScope and changed its behaviour
* Its purpose is to ensure that any modified assets within its (or child scopes) are (if required) compiled in order and relevant systems are notified of their compile start/finish
* It now holds an array for all relevant assets, and a mapping to per-object FCompilerResultsLog (created-on-demand) to differentiate/group messages according to their relevant asset
* Renamed files to UAFCompilationScope.h/cpp

> Introduced Compilation helper struct
* RequestAssetCompilation for single or set of assets, ensures a compilation scope is set-up
~ Ideally this is used by user-code rather than calling ::RecompileVM directly

> FAssetCompilationHandler no longer tracks number of warnings/errors itself, and switched RecompileVM to Compilation::RequestAssetCompilation
