libunwind-(13/14)-dev conflicts with libunwind-dev

[Alex]

Tested on Ubuntu 22.04.

Since these two packages (libunwind-14 and libunwind-dev) conflict with each other, I cannot install some libraries and tools that depend on them. For example, I cannot install libc++-14-dev and libgstreamer1.0-dev together, and that's really unfortunate.

I'm not sure which packages should be somehow fixed (if any), so feel free to reassign this bug wherever it fits.

This is hitting me on Github Actions where the llvm toolchain is installed by default, any chance it could be fixed in Jammy with an SRU?

This is also affecting https://docs.rs (Rust ecosystem documentation building) for packages that want to link against libc++. See: https://github.com/rust-lang/crates-build-env/pull/121
