UI: support persistent state during number/slider interaction

Support for begin/update/end callbacks allowing state to be cached
and reused while dragging a number button or slider.

This is done using `UI_block_interaction_set` to set callbacks.

- Dragging multiple buttons at once is supported,
passing multiple unique events into the update function.

- Update is only called once even when multiple buttons are edited.

- The update callback can detect the difference between click & drag
actions so situations to support skipping cache creation and
freeing for situations where it's not beneficial.

Undo System: avoid redundant decoding on undo

In most cases the undo system was loading undo steps twice.

This was needed since some undo systems (sculpt, paint, text)
require stepping out of the current undo step.

Use a flag to limit this to the undo systems that need it.

This improves performance for other undo systems.
This gives around 1.96x speedup in edit-mesh for high-poly objects.

Edit Mesh: tag the object data for updating instead of the object

When editing vertices with number buttons, tag the mesh, not the object.

This prevents the evaluated mesh being re-created for the object
and is correct as the mesh is being edited not the object.

Note that all tags for updating object geometry should be checked
to see if this change should be applied there too.

From a simple test on a high-poly mesh this gives around 1.3x
overall speedup.

After cache implementation line art apply will not show strokes properly, now fixed.

Fix T89435: Reordering FCurves can cause crash or corruption

Correctly reset `prev` and `next` pointers of action group FCurves when
separating them into distinct `ListBase`s per `bActionGroup`.

These `NULL` pointers are necessary to temporarily demarcate the start &
end of the `bActionGroup::channels` list. Having them still point to
other FCurves caused ordering issues when moving curves towards the
start/end of a group.

This commit corrects the above issue and adds versioning code to rectify
any ordering issues that may have been caused. For this purpose the
`BKE_action_groups_reconstruct()` function is rewritten to avoid relying
on the `bAction::curves` list order or `prev` link integrity.

Walk Navigation: Z axis correction

Fly navigation has always had this option. They is particularly useful
when users use "Trackball" as their orbit method.

For walk navigation this works as a one off option. Not as a toggle like
for fly navigation.

Fix channel packed images display in the Image/Node editor

Channel packed images should not have their RGB affected by alpha.
rendering in Cycles and Eevee was fine already, but displaying these was
not right in the Image and Node editors.

Not 100% sure what to do for the "Color and Alpha" mode, but I guess
this should stay like it was before (applying the alpha).

"Color", "R", "G", and "B" modes were changed to not have color be
affected by alpha though.

UI: Clip: Fix checkbox wrongly greying out entire column

The Pattern and Search display options in the Clip Editor display settings
are independent and should not be grayed out since those options
remain relevant even with path display turned off.

Alternative solution were propoesed in D11630 and D11715
but each of those patches had downsides.
This solution is the simplest and does not break muscle memory.
