macOS Deps: NumPy: Remove buggy Accelerate framework

Building NumPy from source with default options of builder
causes it to link against Accelerate framework which is buggy and
raises a warning mentioned in [2].
"RankWarning: Polyfit may be poorly conditioned"
Accelerate is deprecated with NumPy 1.20+.[1]

So either we build OpenBLAS in dependencies also and set appropriate
env variables suggested in [1] while building NumPy for it to find
OpenBLAS. Or download NumPy wheel from pip and never allow pip to
build NumPy from source while installing.

After this change, pip wheels are used for NumPy for macOS with x86_64.

Fix T85499: Crash on switching to edit mode with uv editor open

A fix for T83187 (rBf83aa830) assumed in the overlay code of the uv editor that the object was a mesh
when it did not have to be - causing a crash.

The fix makes sure that the object is a mesh.

UI/Nodes: Adding node groups via drag & drop (e.g. from Asset Browser)

Adds `NODE_OT_add_group` operator to add a node group from a given name, and
uses that to register a node editor drop-box.
When dropping a node-group asset, the ID will be appended. This is what we do
for other ID assets too.

Should the node group insertion fail (e.g. the group is not compatible with the
current tree, as checked by the poll), the appended data-block is removed.

Fix T84624: node group data-block has phantom user

This is because the node editor added a "real user" to the node group
that it displays. It was mainly added as a hack to solve issues with custom
tree types (T36024). Since we can store id references in custom properties
now, this "real user" is not really necessary anymore.

Given that we are close to a release, I'll only disable line for geometry nodes,
for which the bug has been reported.

Discussed this solution with Hans Goudey.

macOS: use sse2neon to emulate SSE instructions with Arm Neon

* WITH_CPU_SSE was renamed to WITH_CPU_SIMD, and now covers both SSE and Neon.
* For macOS sse2neon.h is included as part of the precompiled libraries.
* Adding Linux support should be possible too, but the best way to handle this
library without official releases or availability in distributions is to be
decided still.

macOS: add Embree, OpenImageDenoise and sse2neon libraries for ARM

This required using a fork of Embree, newer LLVM version, unreleased ISPC
version and sse2neon directly from Git. Hopefully over time all the required
changes end up in official releases. For now we deviate from other platforms.

Patch based on contributions by Apple and Stefan Werner.

Fix: wrong clang tidy cleanup

This reverts a part of rBd3960164163c910d5031a8f076c41b39e0a5503d.
It is not a `std::shared_ptr` but a `boost::shared_ptr`.
This could probably be fixed differently, but `NOLINT` is fine now.
