Upgrade to `ash 0.38`

[MarijnS95]

https://github.com/ash-rs/ash/releases/tag/0.38.0

Code compiles, but there's still quite some more cleanup to do across autogenerated files. A future change should more rigorously use the new builder pattern directly on Vulkan structs, so that the borrow checker can accurately track any lifetime and mutable-reference issues on all PerXXX structs that are now marked 'static.

TODO

• [x] Clean up unnecessary duplication in autogen scripts.
• [ ] Tidy up lifetime changes now that they're easy to spot in the diff; or do we postpone them to a separate PR?
• [ ] Update documentation to reflect any user-facing changes - in this repository.
• [ ] Make sure that the changes are covered by unit-tests.
• [x] Run cargo clippy on the changes.
• [x] Run cargo +nightly fmt on the changes.
• [ ] Please put changelog entries in the description of this Pull Request if knowledge of this change could be valuable to users. No need to put the entries to the changelog directly, they will be transferred to the changelog file by maintainers right after the Pull Request merge. Please remove any items from the template below that are not applicable.
• [ ] Describe in common words what is the purpose of this change, related Github Issues, and highlight important implementation aspects.

Changelog:

### Public dependency updates
- [ash](https://crates.io/crates/ash) 0.38.0

### Breaking changes
Changes to `Surface`:
- Changed `from_win32()` argument types to take `HWND` and `HINSTANCE` as `isize`.

Renamed `PipelineStages::SUBPASS_SHADING` to PipelineStages::SUBPASS_SHADER`, following upstream Vulkan changes.

What still needs to be done for this PR?

[MarijnS95]

I'm fairly certain to have written a TODO list via gh pr create when submitting this, but only the standard template entries remain (still need to be done anyway). Edited them into the PR description.

Regarding the change of *mut c_void to HANDLE, they don't seem to be the same type. In C it's a typedef to void*, which is equivalent to *mut c_void in Rust. Changing it to anything else would be a breaking change.

For what it is worth, raw-window-handle treated this as a breaking change. https://github.com/rust-windowing/raw-window-handle/commit/69d9eac14401e1a8868d14febe30583f9ea70a98#diff-ee9da70e8a36920d0c024abb7c25308cb435c3dcba46a3566abca2a11fd1cfffL36-R34

I think this is the right thing to do to maintain semantic versioning correctness.

Sounds good.

[MarijnS95]

Yes, we followed suit on the isize change.
