Cycles: add time statistics to scene update

Gathers information for time spent in the various managers or object (Film, Camera, etc.) being updated in Scene::device_update.

The stats include the total time spent in the device_update methods as well as time spent in subroutines (e.g. bvh build, displacement, etc.).

This does not qualify as a full blown profiler, but is useful to identify potential bottleneck areas.

The stats can be enabled and printed by passing `--cycles-print-stats` on the command line to Cycles, or `-- --cycles-print-stats` to Blender.

Cleanup: Use DNA defaults for cloth modifier

Followup for rB8398050695
This requires moving a few enum definitions to DNA instead of BKE, and
adding default definitions for the two structs the cloth modifier where
the cloth modifier stores its settings. The defaults are also reordered
to be consistent with the order of each item in the struct.

Cleanup: Clang tidy fixes

Fix a redundant return statement at the end of void function and
an inconsistent declaration parameter names.

Fix T80873: Grab active vertex preview not working with shape keys

Fix T81268: Crash when undo from Sculpt Mode to Edit Mode

This was introduced in 6c9ec1c893f9. The overlays can now be drawn when
PBVH drawing is not enabled, but the PBVH should still exist in the
SculptSession in order to draw them. Before, it was avoiding the crash
by checking use_pbvh as BKE_sculptsession_use_pbvh_draw also checks if
the PBVH exists.

Paint: Ignore inbetween events for anchored strokes

When using anchored strokes, inbetween events are not needed since there
is no stroke path to be reconstructed. Handling the inbewteen events are
only producing unnecessary updates, creating performance issues.

Sculpt: Cloth Simulation Dynamic area mode

This simulation area mode moves the active area with the brush. When
enabled, the cloth brush has no restrictions on stroke length, area or
mesh vertex count.

In order to work, this enables PBVH nodes dynamically for simulation as
the stroke location moves and builds the constraints for new nodes
during the stroke. When a node is not inside the simulated area, all the
constraints that were created for it and vertex collisions are not
computed. The simulation limits falloff areas and constraints tweaking
control how the simulated and no simulated nodes blend.

Cycles: Fix broken 32 bit shift.

1ul << n will still be a 32 bit integer regardless
of the value of n, given the target here is 64 bits
the upper 32 bits will always be zero. Using 1ull
will yield the expected result.

remove foreachObjectLink callback

This removes `foreachObjectLink` from `ModifierTypeInfo`, `GpencilModifierTypeInfo`
and `ShaderFxTypeInfo`. There is no need to have both, `foreachObjectLink` and `foreachIDLink`.
There is not code that actually depends on `foreachObjectLink`.

Volumes: support lower resolution in viewport

The adds a new option to simplify volumes in the viewport.
The setting can be found in the Simplify panel in the render properties.

Volume objects use OpenVDB grids, which are sparse. For rendering,
we have to convert sparse grids to dense grids (for now). Those require
significantly more memory. Therefore, it's often a good idea to reduce
the resolution of volumes in the viewport.

Fix subdivision surface wrong for non-limit surface and subdivision level 1

Use DNA defaults system for modifiers

As noted in T80164, there are quite a few area of Blender where the
"Reset to Default Value" operator in button context menus doesn't work.
Modifiers are one of them, because the DNA defaults system was never
set up for them.

Additionally, this should make modifier versioning easier. Whenever a
new field is added it should be automatically initialized to the
default value.

I had to make some ordering changes in the following modifiers to work
around an error with `-Wsign-conversion` in the macros:
- Solidify Modifier
- Corrective Smooth Modifier
- Screw Modifier

Some modifiers are special cases and are skipped in this commit:
- Data Transfer Modifier
- Cloth Modifier
- Fluid Modifier
- Softbody Modifier
