UI: reorganize proportional editing options

- Move connected & projected into individual toggles.
- Top-level proportional editing button now only toggles.
- Use popover for proportional edit-mode falloff and options.

Note that it's no longer possible to toggle connected via key bindings,
although this could be supported again if it's needed.

Gizmo: display axis in camera view

User request to see axis even when in camera view,
it's also useful when the camera is locked to the view.

Fix T59848: precisely represent the dependencies of Armature modifier.

When the modifier uses vertex groups, the set of the bones it actually
needs is precisely defined by the set of the group names. If envelopes
are enabled, this refinement is not available, because any bone can
potentially be used.

This can be used in the dependency graph construction to allow objects
deformed by a part of the armature to be used in constraints on other
bones, e.g. for placing cartoon-style face elements on top of the body
mesh via Shrinkwrap constraints.

Since the list of vertex group names is now used as an input by
the dependency graph, adding/removing/renaming groups should now
be triggering a graph rebuild.

DRW: Batch Cache: Add Loop normals calculation flag and cleanup style

Improve selection time since it bypass BM_loops_calc_normal_vcos when mesh
uses auto-smooth.

DRW: Improve edit mode selection time when using auto-smooth

Unfortunately it does not concern paint mode.

DRW: Speedup: Improve time to validate batch cache

This is a small improvment but is does scale up with the number of objects.
This improvement *does not* speedup geometry update.

Industry Compat Keymap: Small fixes

- Use W for Move in Sequencer
- Use correct shortcut for sidebar in Sequencer
- Remove inconsistent shortcut for adding nodes

Fix T63979: GPencil control points hidden in orthographic mode

Merge branch 'master' into greasepencil-object

GPencil: Improve Fill Tool speed (6 times faster) in complex files

There was a double loop when drawing the offscreen data for the fill tool. This loop did an exponential drawing, slowing a lot the process.

For example, one file was using 7.39 seconds and now use 1.20 or less to do the same process.

The fix is more noticeable with big files, reducing exponentially the time used by the tool. For very simple files the speed change can be unnoticeable.

Aso fixed a hidden bug with stroke opacity that it was unnoticeable due the double loop.

UI: move properties panel into 'Item' category

Cleanup: Spelling in comment

Missed last commit (workspace template checks)

UI: top-bar reorganization

This hides the top-bar by default for everything
besides paint/sculpt workspaces.

- Use the top-bar mainly for active tool settings &
popovers panel options.
(transform / snap settings are an exception for this convention).
- Only show the top-bar (by default)
in paint work-spaces (sculpt / texture-paint / grease-pencil).
- Add an active-tool panel to the sidebar.
- Split 3D view tabs into (Item / Tool / View).

D4721 with minor changes.

Further work is needed for the top-bar and image-editor.

Fix: Dopesheet context menu was referencing easing_type

This only exists in Graph Editor.

Industry Compat Keymaop: Clear use of Tab in remaining editors

This makes it possible to use Tab for operator search everywhere.

Cycles: Improved eqiuangular sampling for spot lights.

When doing equiangular sampling, it now first clips the ray to the
intersection of the spot light cone.

Fix T63592: Grease pencil - Guides still active in Fill mode

Enable guides only for Draw tool.
