XR: Remove remaining use of GHOST types in RNA

It might be good to have a WM equivalent for GHOST_XrPose (e.g.
wmXrPose) since converting from location/rotation or float[7] to
GHOST_XrPose can be pretty awkward.

GPencil: New option to disable automatic zoom

Alembic procedural: use an enumeration to discriminate object types

Using ObjectHeader::matches involves allocating strings which showed in
profiles.

XR: Start refactoring internal API

Remove unnecessary data from GHOST types and mostly eliminate use of
GHOST types at RNA level. At the WM level, action creation functions
deal with single actions (instead of multiple actions at once) to
simplify the API.

EEVEE: Depth of field: Fix incorrect prediction for holefill tiles

Holefill is only needed if having foreground elements in the tile.

EEVEE: Depth of field: Improve slight defocus opacity estimation

This correct the opacity estimate (for some reason the number of samples
returned by dof_gather_total_sample_count is wrong and ring_count needs
to be incremented).

Also adds a bias towards the focused area to improve the transition to
fully opaque.

EEVEE: Depth of field: Bleed more background over in-focus area

Improves water-tightness.

Armature: add B-Bone lengthwise scaling and custom handle scaling options.

In addition to the base bone transformation itself, B-Bones have
controls that affect transformation of its segments. For rotation
the features are quite complete, allowing to both reorient the
Bezier handles via properties, and to control them using custom
handle bones. However for scaling there are two deficiencies.

First, there are only X and Y scale factors (actually X and Z,
but this is the legacy naming), while lengthwise all segments
have the same scaling. The ease option merely affects the shape
of the curve, and does not cause actual scaling.

Second, scaling can only be controlled via properties, thus
requiring up to 6 drivers per joint between B-Bones to transfer
scaling factors from the handle bone. This is very inefficient.

This patch addresses these deficiencies by adding Length scale
inputs, and providing toggles to apply custom handle local scale
channels to the now four scale-related properties. The 'Length'
name is used to avoid confusion due to the X/Y vs X/Z naming.

The two Length scale inputs control the ratio between the lengths
of the start and end segments of the bone: although for convenience
two inputs are provided, the whole chain is still uniformly scaled
to fit the curve.

A Scale Easing option is provided to multiply the easing value
by the Length scale factors to synchronize them - this produces
a natural scaling effect where both the shape of the curve and
the scale is affected.

The second issue is addressed by providing toggles for each handle
that multiply each of the X, Z, Length and Ease values by the matching
Local Scale channel of the handle bone, thus replacing trivial drivers.
The Scale Easing option has no effect on this process since it's easy
to just enable both Length and Ease buttons.

Finally, this fixes a strange behavior where the segments were not
actually scaled in the Y direction to match their actual length, thus
producing gaps or overlap depending on the shape of the curve. For
transformation the change should be very small if enough segments
are used, but this will affect the results of the Copy Transforms
and Armature constraints, so a backwards compatibility option is
provided. Newly created bones default to the new behavior.

Bone Overlay: support bone wireframe opacity settings.

When weight painting the bone overlay is extremely intrusive,
effectively requiring either extensive use of hiding individual
bones, or disabling the whole bone overlay between selections.

This addresses the issue by adding two bone opacity sliders that
are used for the 'wireframe' armature drawing mode. One directly
controls the opacity in a uniform way. The other one allows fade
based on the depth between the near and far clip planes in order
to provide an automatic visual cue about which bones are closest.

Depsgraph: connect up drivers on various physics properties.

It seems drivers for physics properties weren't being linked to
evaluation nodes. This connects settings used by modifiers
to Geometry; particle settings and rigid body data to Transform
which seems to contain rigid body evaluation; and force fields
to object Transform, since fields can exist on empties.
