Allow our Windows Thumbnail Handler to supply thumbnails up to the
maximum 256x256 size.

It was smart enough to check if the buffer had the right
size but neglected to cast to a 64 bit value so it
overflowed.

Thumbnail extraction now shares code between Linux/Windows,
allowing thumbnails from Zstd compressed blend files to be extracted.
The main logic is placed in blendthumb_extract.cc and is built as static
library. For windows there is DLL which is registered during blender
install and which then reads and generates thumbnails.
For other platforms there is blender-thumbnailer executable file which
takes blend file as an input and generates PNG file. As a result
Python script blender-thumbnailer.py is no longer needed.
The thumbnail extractor shares the same code-path as Blenders file
reading, so there is no need to duplicate any file reading logic.
This means reading compressed blend files is supported (broken since
the recent move Zstd compression - D5799).
This resolves T63736.

Ref D6408
Casting a 64 bit pointer to a 32 bit DWORD gave 2 warnings.
Solved by storing the actual DWORD in the registry table.
Would have preferred to use a union, but C++ doesn't let you
initialize anything other than the first field, and C99 style
initializers are not supported until C++20, so this solution
will have to do until then.
Previously this was done in the deps builder due to the fact we needed
both 32 and 64 bit versions of this dll and CMAKE does not support that
in a single build folder. Now that 32 bit support has been dropped, this
can be safely moved into the codebase.
