Enable modes according to the number of times the button is pressed

Transform: New feature to set a custom 'Snap With'

Ref T66484

Basically the idea is to use a modal keymap to change the current Base Point
defined by `Snap With` by one that can be chosen through snapping.

{F9170047}

I prefer to avoid using any of the modifier buttons (Shift, Alt, Ctrl) as
they can be used in the future to allow navigation during transform operations.

So the shortcut chosen in this patch is the {key B}.

Note:
This feature is not enabled if the scene snap option is Incremental or grid.

Geometry Nodes: Move GeometrySet classes to global namespace

Brecht and I decided to move the GeometrySet classes
to the global namespace for now. This way we can use
the same type in C and C++ and don't have to use
reinterpret_cast as often.

XR: Enable switching action sets during session

Since xrSuggestInteractionProfileBindings() overwrites any existing
profile bindings, the solution is to suggest bindings from all action
sets at the same time (done just before attaching action sets to the
session).

Cleanup: Comments

Fix assert failure when regenerating preview icons

Would happen when changing material settings multiple times while the
material-slot list was visible with the material icon previews.

Separate File Browser Data From Asset Browser data

Internally, the Asset Browser is based on the File Browser. So if you opened
one of them as a regular editor and switched back and forth between them, data
like display options, current path and navigation history (for previous/next
navigation) would be shared between them. This was quite confusing and not what
users would expect.

Now the data is entirely separate: The Asset Browser can have its own display
options, navigation history, etc.

I had to refactor some bits. But I think the resulting code is actually cleaner
than what we had before.

Addresses T82103.
