Fluid: Improved OpenVDB support for fluid caches

This commit makes uses of the new OpenVDB IO in Mantaflow (introduced in 781f783a66ac).

From now on, fluid cache files in OpenVDB format will contain a list of grids per frame (before: one .vdb file per grid per frame). Besides regular grids, particle systems are also stored using OpenVDBs PointGrid data structures.

All older cache formats will remain fully functional:
- Uni caches (.uni) files are still available from the UI and can be used as before
- Raw caches (.raw) are no longer available from the UI, but loading them is still possible
- Old OpenVDB caches (one .vdb per grid) can no longer be baked either, but loading them is still possible.

It is also no longer possible to choose file formats for 'Noise' and 'Particles'. Instead there are now options to set the file format for 'Volumetric' and for 'Mesh' data.

Known issues (planned to be resolved soon):
- OpenVDB files are currently not taking into consideration the clipping value (FluidDomainSettings). Empty cells are therefore being written too. Depending on the scene, this can make file sizes unnecessarily large.
- Domains are not being exported at their world position. Instead they are always clipped to the origin.

Fluid: Updated Mantaflow source with latest OpenVDB changes

This updated set of Mantaflow files includes the improved OpenVDB file IO. With this update it is finally possible to store multiple grids per file. It is also possible to save particle systems and particle data to OpenVDB files.

Cleanup: fix typo in denoiser menu

Fix missing WITH_CYCLES_EMBREE in the build configurations

Cleanup: make it possible to include util_tbb.h in any order

Fix T78112: VSE Sequencer/Preview crash after fullscreen

The region refresh callback wasn't called, which in the VSE ensures valid
region sizes and removes handlers of invisible regions.

Cycles: add Intel OpenImageDenoise support for viewport denoising

Compared to Optix denoise, this is usually slower since there is no GPU
acceleration. Some optimizations may still be possible, in avoid copies
to the GPU and/or denoising less often.

The main thing is that this adds viewport denoising support for computers
without an NVIDIA GPU (as long as the CPU supports SSE 4.1, which is nearly
all of them).

Cycles: add denoising settings to the render properties

Enabling render and viewport denoising is now both done from the render
properties. View layers still can individually be enabled/disabled for
denoising and have their own denoising parameters.

Note that the denoising engine also affects how denoising data passes are
output even if no denoising happens on the render itself, to make the passes
compatible with the engine.

This includes internal refactoring for how denoising parameters are passed
along, trying to avoid code duplication and unclear naming.

Python API: support integer default for bpy.props.EnumProperty

This must match the specified number in enum items, and is supported for both
static and dynamic enums. Previously dynamic enums did not support a default
value at all.

Fix build error on Windows after recent changes

Fix T77913: Incorrect handling of negative-scale bit in DRWResourceHandle

Sculpt: rename default vertex color layer name from Col to Color

No need for abbreviation here, and helps avoid conflicts with old vertex
color layers.

Cleanup: move TBB includes into own header

EEVEE: Fix crash when using motion blur without postfx blur

Fix memory leak calculating deform modifiers in edit-mode

This bug goes back to 2.80 but doesn't seem to have been reported.

MEM_guardedalloc: allow freeing const arrays with MEM_SAFE_FREE

'const' arrays couldn't use this macro with GNUC.

Fix T77672 EEVEE: Reflections with reflection plane broken (regression)

Fix T78190 EEVEE: Render passes broken in final render

This was caused by the step motion blur implementation.
`DRW_cache_restart` was reseting the cache and cause
`EEVEE_renderpasses_postprocess` to not work inside
`EEVEE_render_read_result`.

Fix T78172: Undo crash due to IDTemplate operations missing undo push.

This should be included in 2.83 as well.
