Depsgraph: Clear localization tag for CoW IDs

They are self-contained now, and should not cause any sync or
free happening when freeing them.

Tag all localized ID types as such

Remove legacy node tree localization tag

Is stored on ID level now.

Followup to the previous commit

Thought this is to be fixed in master first. Turns out, nope :)

Cleanup: Double semicolon at the end of line

Fix strict compiler warnings/errors

Merge branch 'master' into blender2.8

Cleanup: Comments

Splash: tweak quick setup to use single column style layout.

Keymaps: add select with left / right option to quick setup splash screen.

Viewport collections visibility popover

This brings the functionality currently in the H shortcut, to hide/show
individual collections.

In order to convey hierarchy, and to make justice to the originally
intended 1-10 shortcuts, we group the collections per siblings.

LayerCollection RNA API util functions

* has_objects()
* has_visible_objects(view_layer)
* has_selected_objects(view_layer)

Hide collections menu: ignore excluded collections

Note: I didn't change the shortcuts, I think this is a separate decision
to be made. I just want at the moment to have the H operator to mimic
the upcoming popover.

Personally if we are to keep the 1-10 shortcuts (and they do work) I
think we should skip the excluded collections altogether.

In fact we could have an option to hide them from the outliner too.

Units: Identifiers in Python

I only specified the identifiers for the units that are actually accessible for now.
This way we can postpone some decisions for now. E.g. if it should be `METER_SQUARE`, `SQUARE_METER`, `METER_SQ`, ...

Depsgraph: Build all type of IDs for modifiers and constraints

It was missing handling of collections there, which caused collection
used for smoke colliders to not be in the dependency graph.
