Depsgraph Filtering: Fix ID node filtering problems

* COW data hasn't been expanded yet when we try to filter the graph
(you need to have tagged + evaluated it for this data to exist),
so all the offending nodes would just get left in

* Added more debug prints to verify whether the id_nodes vector is
getting cleared correctly

Depsgraph Filtering: WIP more debugging prints

Depsgraph Filtering: Remove opnodes from entry tags too

Depsgraph: Fix filtering-related crashes

* Simplified operation-relation deletion. Now we collect the relations
to delete into a vector, then iterate through that, thus solving issues
with iterator invalidation (+ aborts arising from that)

* DEG_foreach_ancestor_ID() was assuming that all dependencies were
OperationDepsNodes, when in fact, some could be TimeSource nodes

Depsgraph: Print simple stats after filtering graph, to quickly verify if anything happened

Depsgraph: First draft of graph filtering API implementation

When this works correctly, we should be able to feed in an existing
depsgraph instance, and get out a "filtered" copy of it that contains
only the subset of nodes needed to evaluate what we're interested in.

The current implementation only filters on ID blocks/nodes,
and starts by building a full new depsgraph instance first.
I'd originally intended to do it per operation instead, copying
over individual nodes as appropriate to have the smallest and least
memory intensive graph possible. However, I ended up running into
into problems with function binding + COW arguments, hence the
current slow solution.

Typo fixes

Tool System: Sculpt border hide/mask tools

Cycles: Add option for building CUDA kernels sequentially

Building the CUDA kernels takes quite a bit of memory, and when building all of
them the combined usage can be too much on some systems (especially VMs).

Therefore, this patch adds an option to force the build system to build them
sequentially by making each build step depend on the previous kernel.

Tool System: support non paint tools in paint mode

This is needed so non-paint-brush tools can be used in paint modes.

Tool System: remove cursor tool from paint modes

Object Mode: Add back spot cone display

Paint Overlay: Fix blending of the brush overlay

UI: Minor label tweaks to operators context menu

* Add Shortcut -> Assign Shortcut

* Add to Favorites Menu -> Add to Quick Favorites
To match the menu name and be more general for when the Quick Favorites
are accessible in places other than just menus (like panels).

Add blank icon to Remove Shortcut so it aligns with Change Shortcut
which is usually the item on top of it in the menu.

Cleanup, unused variable

MSVS 2017 Bug - Subdiv Mesh

Apparently, struct initialization can not be empty,

Multires: Bring back operator to reshape from object

Limited to mesh type of source, not sure it ever worked for non-meshes.
While it's possible to support reshape from any object, the actual brain
of operation would need to be recoded to go away from requirement of
vertex indices matching in source and destination.

Multires: Remove another unused argument from reshape function

UI: Show development entries in context menu when Dev. Extras is enabled

Multires: Fix reshape when active level is lower than the total one
