Sergey CherepanoffandJohn Tur 769a8a650e windows: Automatically find Windows SDK when building gpui (#38711)
### Summary

This PR changes `gpui/build.rs` to look up the Windows SDK directory in
the registry instead of falling back to a hard-coded path.

---

### Problem

Currently, building `gpui` on Windows requires `fxc.exe` to be in `PATH`
or at a predefined location (unless `GPUI_FXC_PATH` is set). This
requires to maintain a certain build environment with proper paths/vars
or to install the specific SDK version.

It is possible to find the SDK automatically using the registry keys it
creates upon installation. Specifically in
`SOFTWARE\\WOW6432Node\\Microsoft\\Microsoft SDKs\\Windows\\v10.0`
branch there are:
* `InstallationFolder` telling the SDK installation location;
* `ProductVersion` telling the SDK version in use.

These keys provide enough information to locate the SDK binaries, with
added robustness:
* handles non-standard SDK installation path;
* deterministically selects the latest SDK when multiple versions are
present.

---

### Changes Made

* **Updated `crates/gpui/build.rs`**:

  * added dependency on `winreg`
  * introduced `find_latest_windows_sdk_binary()` helper
  * updated fallback logic to use registry lookup

This PR only changes the fallback location, and does not touch the
established environment-based workflow.

Release Notes:

- N/A

---

### Impact

Reduces manual configuration needed to build GPUI on Windows.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
