feat: set up delvewheel as the default repair wheel command for Windows (#2831)

* Add a default repair wheel command for Windows

* Install `delvewheel` into Windows build tools

* Add delvewheel to constraints file

* Regenerate constraints

* Docs

* Suggest how to disable Windows wheel repair

* Add tests

* Run `delvewheel` with verbose mode as default

* Add note about telling delvewheel where to look

Suggested-by: Nils <nilsnolde@proton.me>

* Partially revert 81374bb8fc43acefed76cb13d761a9e6cf6afa58

* Add `pip` and `uv` cases for build installations

* Ignore `python-native.dll` for GraalPy

* Ignore MSVC DLLs, try Windows amd64 graalpy happy

* Fix last remaining Windows test failure (famous last words?)

* Update constraints

* Drop workaround unneeded with delvewheel v1.12.1

* Update docs/options.md

Co-authored-by: Aohan Dang <adang1345@gmail.com>

* Drop `test_delvewheel_default_on_windows`

* Partially revert "Update constraints"

This partially reverts commit 2dc4c0f4951858959e213463d90431a5ca03b96f.

* Add a test case when repair command is `""`

* Add back test that checks delvewheel run/disable

* Add a C project with a missing DLL

* Add tests for `missing_dll_project`

* Partially undo virtualenv/python-discovery update

* Fix test

* Discard changes to cibuildwheel/resources/constraints-pyodide312.txt

* Discard changes to cibuildwheel/resources/constraints-pyodide314.txt

* Fix bad merge of constraints

* Discard changes to cibuildwheel/resources/constraints-pyodide313.txt

* Manually add more GraalPy pip markers

* Dependency parsing was too naïve

* Maybe a better way to invoke the compiler on Windows

* Can we get away without a DLL?

!!! tip
cibuildwheel doesn't yet ship a default repair command for Windows.
!!! note "Windows: telling delvewheel where to find DLLs"
On Windows, delvewheel searches the directories on `PATH` for external DLL dependencies. If your DLLs are already discoverable via `PATH`, (say, installed by a package manager that adds itself and the relevant directories to `PATH`), the default repair command should be sufficient.
**If that's an issue for you, check out [delvewheel]** - a new package that aims to do the same as auditwheel or delocate for Windows.
If your project links against DLLs in a custom location such as a [vcpkg](https://vcpkg.io/) or [Conan](https://conan.io/) install tree, or a manually built library directory, you may pass `--add-path` to tell delvewheel where to look. The flag can be used multiple times for more than one directory:
Because delvewheel is still relatively early-stage, cibuildwheel does not yet run it by default. However, we'd recommend giving it a try! See the examples below for usage.
```toml
[tool.cibuildwheel.windows]
repair-wheel-command = "delvewheel repair --add-path C:/vcpkg/installed/x64-windows/bin --add-path C:/mylibs/bin -w {dest_dir} -v {wheel}"
```
[Delvewheel]: https://github.com/adang1345/delvewheel
You can also reference environment variables expanded by the shell at build time, for example if the path is set during `before-build`:
```yaml
CIBW_REPAIR_WHEEL_COMMAND_WINDOWS: "delvewheel repair --add-path %VCPKG_INSTALLED_DIR%\\x64-windows\\bin -w {dest_dir} -v {wheel}"
```
