ec723ad25c 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`.

8398050695 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

ba4a2a4c8b UI: Use instanced panel custom data instead of list index
For modifier shortcuts we added a "custom_data" field to panels.
This commit uses the same system for accessing the list data that
corresponds to each panel. This way the context is only used once
and the modifier for each panel can be accessed more easily later.

This ends up being mostly a cleanup commit with a few small changes
in interface_panel.c. The large changes in the UI functions are due
to the fact that the panel custom data is now passed around as a
single pointer instead of being created again for every panel.

The list_index variable in Panel.runtime is removed as it's now
unnecessary.

980dd43bd4 Particles: give emitter its own state
High quality emitters need to maintain state themselves. For example,
this it needs to remember when it spawned the last particle.
This is especially important when the birth rate is changing over time.
Otherwise, there will be very visible artifacts.

It is quite likely that other components of the simulation need their own
state as well. Therefore, I refactored the `SimulationState` type a bit,
to make it more extensible. Instead of using hardcoded type numbers, a
string is used to identify the state type. Also, instead of having switch
statements in many places, there is a new `SimulationStateType` that
encapsulates information about how a specific state is created/freed/copied/...

I removed the integration with the point cache for now, because it was
not used anyway in it's current state.

5063820c9b Particles: Emit particles over time

19d17b217a Particles: use CD_PROP_FLOAT3 instead of CD_LOCATION
`CD_LOCATION` was only used temporarily due to the lack
of a better alternative. This also removes the name from
`CD_LOCATION` again, because at most one layer of this
type should exist.

580d50091c Particles: Create a simulation state for every Particle Simulation node
Every Particle Simulation node has a name (or a path when it is in a node group).
This name has to be used in the Simulation modifier on a point cloud to see
the particles.

Caching has been disabled for now, because it was holding back development
a bit. To reset the simulation, go back to frame 1.

Currently, there is no way to influence the simulation. There are just some
randomly moving points. Changing that is the next step.

b6981d9e48 Modifiers: New callbacks for reading and writing .blend files
This is part of a greater blenloader decentralization effort (T76372).
For modifiers the goal is that fewer files have to be modified when
a new modifier is added.

This patch just adds the `blendWrite` and `blendRead` callbacks to
`ModifierTypeInfo` but does not change any other code yet. In the next
steps, modifier specific code will be moved from `writefile.c` and
`readfile.c` into their corresponding `MOD_*` files.

6f96dfabe5 Simulations: initial simulation state and cache
The current particle state is stored in a `CustomData` instance and
the cache is stored in `PointCache`.

The current state exists on the copy-on-write copies of the simulation,
while the cache only exists in the original data block.

This patch implements a temporary trivial particle simulation that does not
use the node system yet. It is used for testing and will be replaced soon.

`PointCache` still has some limitations that need to be overcome using
separate refactorings. For example, we need to be able to store the number
of particles in the point cache. Also we need to change which attributes
are stored for a particle system more dynamically than is currently possible afaik.

9b099c8612 UI: Drag and Drop Modifiers, Layout Updates
This patch implements the list panel system D7490 for modifiers.
It also moves modifier drawing to a callback in ModifierTypeInfo
in line with the extensible architecture refactoring goal T75724.

This adds a PanelRegister callback and utilities for registering
panels and subpanels. It also adds the callbacks for expansion saving
and drag and drop reordering described in D7490.

These utilities, callbacks, and other common UI elements shared
between modifiers live in MOD_ui_common.c.

Because modifier buttons are now in panels, we can make use of
subpanels for organization. The UI layouts also use the single
column layout style consistently used elsewhere in Blender.
Additionally, the mode-setting buttons are aligned and ordered
consistently with the outliner.

However, the large number of UI changes in this patch may mean
that additional polishing is required in master.

Thanks to William Reynish (@billreynish) who did a fair amount of the
layout work and to Julian Eisel (@Severin) for consistent help.

b55c78a289 Simulation: Add modifier to access simulation data
For now the "Simulation" modifier only exists for point cloud objects, because
we need this for the particle system. Right now, the modifier is doing nothing.

There is a new `DEG_add_simulation_relation` function that is used
by the modifier to make sure that the simulation is evaluated before
the modifier is executed.
