EEVEE: Initial implementation of deferred shading

This introduce a fat Gbuffer layout that groups closure data in groups
of similar BSDF. The goal is to have at least one sample for each
group to avoid too much code complexity and expected worse performance.

There is a lot of room for buffer reuse to reduce memory usage but it is
not considered a priority for now.

DRWTexture: Add missing integer render-targets format support.

GPencil: Curve smoothing BKE

Update with changes from D10942

Except for motion capture object autokeying (will be added again once
a good way to get the blender context from wm_xr_session is found),
functionality remains the same as before.

Show a bounding box for object assets while dragging

Note: Object assets have to be saved with this commit or later for the bounding
box to appear.

Basic idea is:
* Store the bounding box (and related info) in the asset metadata.
* The bounding box has to be updated and written to custom properties of the
asset metadata.
* There's a new `AssetTypeInfo` struct, to set asset type dependent callbacks
or data (in future). ID types can conveniently define asset-type info as part
of their `IDTypeInfo` definition.
* The asset-type info can contain a custom callback to be executed before the
asset is saved. This is how the object can write its custom asset metadata.
* The dropbox can also register a callback to set properties for its
gizmo-group now. Used to copy
* The "placement plane" gizmo is scaled to the bounding box size too.
* For local ID assets, the data should be accessed directly, so the file
doesn't have to be saved to get the bounding box updated.

Also:
* Added proper gizmo group custom property support to C (was already supported
in Python, or in C with some hacking).
* Store the basis matrix (world matrix without parent or constraint transforms)
in the custom asset metadata. Used by the placement gizmo to scale the
bounding box to match the result visually when dropping.
* The preview image is disabled while dragging objects over the 3D view.
* The bounding box always snaps with its lower edge (Z axis) to the surface.
Snapping with other axes can be added still.
* However, actually dropping the object still uses the origin, so the drop
position may not match what the bounding box indicated. This could be changed
to also use the bounding box instead. Or the drawn bounding box should be
translated to respect the origin position.

Fix memory leak introduced by last commit

Add IDP_ID UI data for tooltips from node sockets

Refactor IDProperty usage in MOD_nodes.cc

GPencil: Add new Dilate factor for Fill Brush

Before, the dilate of the fill area was predefined as 1 pixel. Now this value can be changed to fill gaps.

Merge branch 'master' into temp_bmesh_multires

Also fixed a pose brush bug that may or may not have been
the result of the merge nixing code, need to check master.

Assets: Keep assets active after renaming, ensure they are scrolled into view

See https://developer.blender.org/D11119, just committing this to the branch
for testing already.

Asset: Keep assets active after renaming, make sure they are scrolled into view

I want to clean this up a bit still, but it seems to work now.

Also includes (to be split off):
* Don't allow renaming assets from the file list for now (e.g. right-click >
Rename). This doesn't work yet and I'm not sure it should even. If an asset
is a local data-block it can be renamed in the sidebar.
* Fix broken logic to scroll a preview into view.
* Partially includes D9994. These changes were needed for this to work.
