Integrate custom ptx-builder into rust-cuda-kernel

[juntyr]

The upstream ptx-builder has been unmaintained for years and this crate has instead relied on a custom fork, https://github.com/juntyr/rust-ptx-builder, that was updated for newer Rust versions and contained extra features, e.g. to support live build progress feedback.

While ptx-builder needs to support a variety of use cases, rust-cuda-kernel requires much less. Maintaining the fork took extra effort when the needed functionality could just be upstreamed into rust-cuda-kernel.

This PR iteratively stripped the ptx-builder codebase down to only the needed parts and then refactored them to better integrate with the existing code.
