Fix T90595: some VSE strip properties do not identify strip name in anim

channel names

Working with multiple strips keyframes was unneccessarily difficult in
Animation Editors (since some anim channels could not be distinguished).

Namely `Crop` and `Transform` are nested structs (nested under
`Sequence`), so these were just displaying the raw struct name.
Also strip modifiers did not have their strip name in their channel
names. Now include the strip name for these.
