Geometry Nodes: support geometry nodes modifier on volume objects

Differential Revision: https://developer.blender.org/D11011

Cleanup: clang tidy readability-inconsistent-declaration-parameter-name

Cleanup: uiBut.flag had an internal flag out of the documented range

Increase range of internal flags & order UI_SEARCH_FILTER_NO_MATCH
within this range, so public button flags aren't accidentally added
that overlap with internal flags.

Cleanup: remove redundant code/comments from BKE_mesh_nomain_to_mesh

Merge branch 'blender-v2.93-release'

Fix T87055: Crash applying modifier on mesh with multires data

PyAPI: update docs to include poll_message_set reference

Part of D9738

PyAPI: support Operator.poll functions 'disabled' hint

Python scripts can now define the reason it's poll function fails using:

`Operator.poll_message_set(message, ...)`

This supports both regular text as well as delaying message creation
using a callback which should be used in situations where constructing
detailed messages is too much overhead for a poll function.

Ref D11001

Cleanup: add CTX_wm_operator_poll_msg_clear

Call this function instead of `CTX_wm_operator_poll_msg_set(C, NULL)`

Merge branch 'blender-v2.93-release'

Fix crash with Alembic export after recent persistent data bugfix

We weren't clearing the recalc flags for that case.

Cycles: include more transparency and emission in fast GI approximation

For indirect light rays, don't assume any hit is opaque, rather if it has
transparency or emission do the shading but don't do any further bounces.

Naturally this is slower when there are transparent surfaces, however
without this cutout opacity doesn't give sensible results.

Cleanup: move BVH utility functions into own file

Cleanup: Clang tidy, clang format

Fix T87535, T87295: issues with new persistent data option

Some persistent data code was disable due to a deeper design issue, which
meant some updates were not communicated to renderers.

Dependency graph updates work in two passes, once where Blender scene
animation updates are done, then app handler scripts can run to make further
scene modifications, and then the depsgraph is updated again to take those
into account.

Previously the viewport would update renderers twice when such app handler
scripts were present. Now both viewport and persistent data rendering update
the renderers only once, accumulating updates from both passes.

Fix T87567: Crash adding item in empty attribute search

The function applying the search used the dummy search info for when
the item doesn't exist even when there was no UI data associated with
the node at all.

A fix is to only add the search menu when there is attribute info
stored for the node. This is something I wanted to do anyway, since
it makes it look more purposeful when there are no attribute info
for a node, less like a bug.

Fix T85223: Some modifier panels can dissapear in old files

The problem is that each uiBlock needs to be assigned a unique name,
but when there can be multiple modifiers of the same type, we use the
panel sort order for the unique part of the string. However, the most
recent test file has 1200+ panels in the property editor, so 4
characters isn't enough for a unique string.

That's not a situation I expected, but it makes sense, because we don't
remove legacy panels with unused types when loading old files. So they
tend to accumulate a bunch of unused panels. That's why this works fine
with a new property editor, it doesn't all of the extra old panels.

These panels must be stored for the expansion status and order, but
arguably we could cull unused panels on save. However, simply increasing
the length of the unique panel string is a valid fix in this situation.
In the future, we can look into removing unused panels when saving.
