Particles: add implicit covnersions between Vector and Color

Not sure if these conversions are a good idea. However, we have them
in Cycles, so they be available in the simulation node tree for consistency
reasons.

Particles: simplify adding new implicit conversions between sockets

Fluid: Update Mantaflow source files

Refactored various functions after noticing new warnings when compiling on Apple DTK devices - there should now be fewer warnings when building.

Particles: change initial velocity of particles

This is only temporary, but makes testing the system a bit easier.

Particles: support Separate/Combine RGB nodes

Particles: simplify Combine XYZ node

Particles: support Color Ramp node

Fix T78537: too much memory usage rendering animation with persistent images

For still images, always return 0 for the current frame number. This ensures
Cycles can detects that the image did not change.

Based on patch by Vincent Blankfield.

Keymap: disable 'Alt' click for tools prompt by default

Based on feedback from artists in the Blender Studio this is too
easy to access by accident.

This is still accessible as a preference.

deps builder: Fix typo in windows harvesting

Simulation: Change BPH prefix to SIM

In a previous commit the `physics` folder has been renamed to `simulation`.
This commit updates the function/file prefix accordingly.

Simulation: Rename `physics` directory to `simulation`

Function names will be updated in a separate commit.

This will be the place for the new particle system and other
code related to the Simulation data block. We don't want
to have all that code in blenkernel.

Approved by brecht.

Fix git tag warning when running make update after recent changes

Particles: implement more vector math operations

UI: show connected icon for proportional editing in the image space

Particles: support for most math node operations

Nodes: support default function for partially implemented nodes

Particles: support Map Range node

Only linear interpolation mode is supported for now.

T73268: Link C/C++ unit tests into single executable

This commit introduces a new way to build unit tests. It is now possible
for each module to generate its own test library. The tests in these
libraries are then bundled into a single executable.

The test executable can be run with `ctest`. Even though the tests
reside in a single executable, they are still exposed as individual
tests to `ctest`, and thus can be selected via its `-R` argument.

Not yet ported tests still build & run as before.

The following rules apply:

- Test code should reside in the same directory as the code under test.
- Tests that target functionality in `somefile.{c,cc}` should reside in
`somefile_test.cc`.
- The namespace for tests is the `tests` sub-namespace of the code under
test. For example, tests for `blender::bke` should be in
`blender::bke:tests`.
- The test files should be listed in the module's `CMakeLists.txt` in a
`blender_add_test_lib()` call. See the `blenkernel` module for an
example.

Fix T78920: missing depsgraph relation when using sound strips in VSE

Having a sound strip in the VSE caused a missing relation error to be
logged on the console. This was caused by the AUDIO depsgraph component
not having an entry node. This commits adds that node, and sets up
relations correctly.
