Improve crash stacktraces

[rr-]

To provide players with detailed stack traces, we need to embed debug information, including symbol names, into our DLL and EXE files. Recently, we've implemented platform-specific stack resolution techniques: using the backtrace library on Linux and Windows APIs on Windows. However, a challenge arises with Windows: it can only resolve symbol names from PDB-based debug information. Our compiler, MinGW, generates debug information in DWARF format (since it's based on GCC), which Windows cannot interpret. As a result, current stack traces on Windows lack meaningful information.

We have a few potential solutions to address this issue:

• Switching to the MSVC compiler for Windows, which is impractical
• Using the cv2pdb project, which can convert and embed PDB into EXEs
• Developing our own stack resolver capable of parsing DWARF debug information

I had little luck with cv2pdb. It turns out, however, that there is already a project which implements the third solution – it's called dwarfstack and is available here: https://github.com/ssbssa/dwarfstack/

And so, this PR switches the Windows stack resolver from its APIs to this library. Instead of trying to link it statically via Docker's toolchain like we do for SDL and others, I found it easier to use Meson's wrap system. This mechanism lets us use external code just as if it were our own, without having to actually add it to our codebase – even if the upstream repo doesn't use Meson itself. It's really neat IMO.
