UI: move gizmo orientation settings into popover

Instead of link toggle with enum, use a single popover that contains
both settings. The code for this isn't nice - needing 3x panels for now.

Fix Proportional Edit Projected 2D method skiped center calculation

rBa520e7c85c83 defined T_OVERRIDE_CENTER(1 << 25)
which was already in use T_PROP_PROJECTED(1 << 25)
thus skipping center calculation

Fix T59578: enabling "vertex group weights" in edit mode results in crash

RNA: support setting default values for custom properties.

NLA requires a usable default value for all properties that
are to be animated via it, without any exceptions. This is
the real cause of T36496: using the default of 0 for a scale
related custom property obviously doesn't work.

Thus, to really fix this it is necessary to support configurable
default values for custom properties, which are very frequently
used in rigs for auxiliary settings. For common use it is enough
to support this for scalar float and integer properties.

The default can be set via the custom property configuration
popup, or a right click menu option. In addition, to help in
updating old rigs, an operator that saves current values as
defaults for all object and bone properties is added.

Fix T59237: Instancing on a path doesn't do anything

This commit makes it so curve path parent solving accepts an explicit
arguments for both time and curve speed flag, making it so we don't
have to mock around with scene's frame.

One unfortunate issue still is that if the instancing object is used
for something else, we might be running into a threading conflict.
Possible solution would be to create a temp copy of an object, but
then it will be an issue of preventing drivers from modifying other
datablocks.

At least the original issue is fixed now, and things behave same as
in older Blender version. Additionally, the global variable which
was defining curve speed flag behavior is gone now!

Fix T59500: Weight Smoothing Not Working

Reviewers: brecht, dfelinto

Maniphest Tasks: T59500

UI: show panel type in Python tooltips

Handy when editing UI scripts.

RNA: convenience method for orientation name & icon

Avoids RNA introspection at draw time
which is relatively slow (approx 5x).

Gizmo: optional custom orientations for transform

This aims to resolve a conflict where some users want to keep keyboard
axis setting global, even when the orientation is set to something else.

Move/rotate/scale can optionally each have a separate orientation.

Some UI changes will be made next.

Transform: use the scenes transform orientation

- Use the user orientation when pressing XYZ keys,
second press switches to global.
- Pressing again switches to global, or local
if you're have global orientation set.

The option for gizmos to have their own orientations will be added,
see: D4075

GP: Update Gizmo position when select

Theme: use menu text color for floating redo panel

blender_light theme was showing black text on dark background.

startup: default file selector to empty filename

Someone saved startup.blend w/ filename, tsk.

Fix T57139: Transform overlay shows even when disabled

Transform bypasses the gizmo API for drawing overlays,
so custom checks are needed.

Also don't draw the gizmo in other windows when transforming.

Fix invalid string comparison

Fix invalid string comparison

UI: tweak shading popover

Show backface culling option even with rendered shading since it doesn't
yet support meshes two-sided option (noted as TODO).

Also correct bad string comparison.

DNA: move back-face culling to shading popover

Overlay options shouldn't be used when overlays are disabled.

Move to shading popover, reported as T58070.
