This change makes it so build system and update utilities for Blender builds
are using pre-compiled libraries and other resources attached as Git modules
instead of using checkout of SVN repositories in the parent folder.
The directory layout:
```
* release/datafiles/
* assets/ -> blender-assets.git
* publish/
* ...
* README.txt
* lib/
* darwin_x64/ -> lib-darwin_x64.git
* darwin_arm64/ -> lib-darwin_arm64.git
* linux_x64/ -> lib-linux_x64.git
* windows_x64/ -> lib-windows_x64.git
* tests/
* data/ -> blender-test-data.git
```
The changes about configuring the actual Git sub-modules are not included
into this patch, as those require repository to actually exist before it
can be used.
The assets submodule is enabled by default, and the rest of them are
disabled. This means that if someone runs `git submodule update --init`
they will not get heavy libraries. The platform-specific and tests
related submodules are enabled when using `make update` or `make test`.
All the submodules are tracked: this means that when new commits are
done to the submodule, the blender.git repository is to be updated to
point them to the new hash. This causes some extra manual work, but it
allows to more easily update Blender and its dependencies to known good
state when performing operations like bisect.

Pull Request: https://projects.blender.org/blender/blender/pulls/117946
Several sub commands tried on their own
to locate python, given I wanted to look
in several locations for a broader libdir
compatibility this is best done in a
central location.
Python 3.9 is still preferred, but if
3.10-3.12 are available that be accepted
as well.
note: this is about the python version
make.bat uses to run various python helper
scripts, this change has no influence on
the python version blender itself uses.
SVN takes a long time to sync even if there are no updates,
the `code_update` parameter gives the option opt out of the
SVN updates.
This is a developer option, people just wanting to build
blender and not do any development are highly recommended
to keep using the `update` method.
make.bat was starting to become hard to maintain, this refactors it into separate batch files for each stage of the process.
-Improved detection of msvc2013/2015
-Improved failure handling.
-Added check for working msbuild and C++ compiler
-Added verbose switch to ease trouble shooting.
-Added Check if svn/cmake/git are in the path before using them
-Display the build configuration before asking to download the libraries
-Offer an option to recover an interrupted checkout of the libraries.
-Automatically check out sub-modules in-case they are missing.
