Outliner: Add synced selection

This implementation is to see how syncing will be done, to be redone
later in a more general way. Right now each operator must explicitly
sync the selection.

Unit System: remove 'm' as an alternate name for mile

Now when using imperial dimensions,
using 'm' suffix is treated as meters instead of miles
(use 'mi' or 'mile' instead).

Resolves T65731

Outliner: Add dirty flag

This dirty flag is to indicate whether an outliner needs to sync
its selection state with the active view layer before redrawing

Revert "Keymap: Add additional scrubbing affordance (Alt-LMB)"

This reverts commits
dcec863b2f2fce7fc5caa138ad3816c88e2aa2a3,
f11929c145ef45444598a9679e675b2d013ae2ef.

It wasn't possible to set the cursor without accidentally selecting a
column of keys & (vice-versa).
This conflicts with Alt->LMB to select column of keys.

Shift-RMB is already bound to scrubbing.

Outliner: Remove negative from sync selection

Removing because it was behaving strangely. I might not entirely
understand what `negative_sdna` does

Fix T65727: Broken button tool-tips in 3D view

Own error in 686820289982.

UI: alternate fix for T65702, handling of auto-saving userprefs

The behavior for loading factory settings wasn't clear for users.

This commit changes the behavior:

- Loading factory settings always disables auto-save
for the current session.
- The internal setting to skip saving on exit is now exposed
in the preferences (when enabled).
- The menu item "Load Factory Settings (Temporary)" has been removed
since it's always temporary.

This way users can always reset factory settings without
having to consider the combination of options that might cause their
preferences to be overwritten at exit.

If they want to enable auto-save for the current session
this can be done from the preferences.

WM: optionally override the context with a module for wm.context_toggle

This may be used with other wm.context_* operators in the future.

Cleanup: expand left/right select keymap items

This was meant to simplify the keymap but ended up
not having a significant advantage.

Keymap: Add Ctrl-SelectMouse in to box-deselect

Cleanup: spelling in comments

Cleanup: clang-format

Cleanup: unused vars

View3D Snap: Don't mix original/evaluated in the same function parameters.

Fix T64478: Wrong location Snap Selection to Cursor after set camera Follow the path.

In this case it is necessary to use the `object->parent` evaluated to obtain the correct `parentmat`.

Fix/Cleanup: I18N: Bad usage of IFACE_ instead of TIP_.

Cheap tip: anything that is not "Camel Case" and/or that is more than
a few words long should use `TIP_` translation, not `IFACE_` one.

Also added several missing strings (including the one reported in D5056
by Jean First (@robbott), thanks).

Cleanup: remove unused var.

Fix T64430: Removing objects from sub-collection doesn't update instances of parent collection.

Collections are a tad annoying with all their caching of objects... When
we modify content of a children collection, we need to tag DeG for CoW
update of all of the ancestors.

For now keeping that recursive tagging helper private, but would not be
surprised if we found more similar cases and needed to expose it to more
code...

Fix (unreported) message wrongly using IFACE_ for its translation.

`IFACE_` is for short strings always shown in UI (like labels of buttons,
menu entries...). Every thing else, especially when more than a couple
of words, must use `TIP_`.
