Run Windows on CI

[yutannihilation]

Close #0

What I did

• Enable Windows build on CI (test & release) by using vcpkg
• Remove build cache on release build (Since the release process is invoked less frequently, the cache is likely to be outdated, which might make some problem. But, I don't have strong opinion here)
• Some minor tweaks
  • Update actions/checkout to v6

Notes

This pull request attempts to use vcpkg to install PROJ v9.6.2. While vcpkg feels a bit too heavy to solve the problem, but it seems this is the only reliable way.

For reference, these are the possible alternative path, but both requires windows-gnu target instead of windows-msvc. Now that windows-gnu is less maintained, I think we should use windows-msvc for now (I hope we can migrate to windows-gnullvm someday).

• Use MSYS2 and install mingw-w64-ucrt-x86_64-proj
• Use proj-sys's bundled_proj feature and install SQLite via Chocolaty

It seems proj-sys's bundled feature doesn't work on Windows, so we need to skip here.
