Cleanup - Point Instance: Use own DNA struct

We will need to expand this node soon to add weight/count for different
elements inside the collection. For that it is better to have the node
to use its own DNA.

Merge remote-tracking branch 'origin/blender-v2.92-release'

Fix merge from 2.92 (subversion bump 292.14)

Object Info: Fix tooltip for the transform space option

This was agreed outside the patch discussion. And it did not make into
the submitted code on 8b777ee6d69d4805c64756cf6a33db894160ce29.

Geometry Nodes - Object Info: option to apply obj transform to the geometry

By design the modified object transformations should still work and
affect the geometry nodes results. The current behaviour, however, would
make the geometry from the object info to not be affected by the
modified object transformations. This patch changes that by default.

In a similar fashion the Location, Rotation and Scale sockets outputs
should be aware of whether the output should be in the global space or in the
space of the nodetree.

To solve this, the patch introduces a new transformation space "enum"
where users can pick "Original" or "Relative" space.

Original
--------
Output the geometry relative to the input object transform, and the
location, rotation and scale relative to the world origin.

Relative
--------
Bring the input object geometry, location, rotation and scale into the
modified object maintaining the relative position between the two objects in
the scene.

Relative space violates a bit the design of the nodetree. The geometry in this
case is transformed so that moving the modified object doesn't interfere with
the geometry. This is particularly useful for the boolean node for instance.

"Original" is the default space, but old files are set to "Relative" for
backwards compatibility.

Merge branch 'blender-v2.92-release'

Blender 2.93 bcon1 - alpha

Bump the version number for the new release cycle.

Blender 2.92 beta - bcon3

Bump the release cycle to beta. This also hides away the experimental features
from the user interface.
