Simplify CI, do more with less.

- Rename Docker job to **"LLVM ${{ matrix.llvm_version }}
Compatibility"** for better visibility.
- Limit `build_type` to **Debug** for MSYS2, OpenBSD, NetBSD, and Nix
jobs to reduce CI time.
- Refactor **Alpine Linux** job: updated to 3.23, simplified dependency
installation, and removed redundant LLVM matrix.
- Modernize **Docker** builds:
    - Added automatic architecture detection (x86_64/ARM) for CMake
downloads.
    - Generalized LLVM repository logic to support multiple Ubuntu
codenames (Focal/Jammy/Noble).
    - Fixed git permissions issues in containerized builds using
`safe.directory`.
- Standardized Android build packaging and added conditional testing for
Debug builds.
