Simplify build workflow

[s-zanella]

• Use CMake presets to unify multi-config builds with Ninja using MSVC and Clang. Works on VS, VS code, and CLI.
• Document how to install dependencies on Windows using winget.
• Let CMake generate appropriate config.h files instead of manually copying default configs for MSVC and Clang.

Thanks! Getting this unified would be great. But running this fails for me right now because it's trying to find the default_config.h

hacl-packages\tools\configure.py", line 154, in __init__
    shutil.copyfile(
  File "C:\Python312\Lib\shutil.py", line 260, in copyfile
    with open(src, 'rb') as fsrc:
         ^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: 'config\\default_config.h'

Thanks! I hadn't tested the configuration script. I restored config/default_config.h.

Thanks, this looks good. We have to figure out the CI failures, then we can get this in.

Oh, no idea why I closed this. That wasn't intentional. But looks like the branch is gone?

No worries. This was opened against protz_all_kyber_variants which got deleted after another merge. I reopened it against dev as #469
