Subject: [PATCH 1/2] Add MSYS2 Mingw-w64 job to GitHub Actions workflow

- Create new 'windows-mingw' job in build.yaml
- Set up MSYS2 environment using msys2/setup-msys2 action
- Install necessary packages including MinGW-w64 GCC, Fortran, CMake
- Configure build with MSYS Makefiles generator
- Build and run quick tests

This change improves Windows support by enabling builds with MSYS2 Mingw-w64,
making Elmer more accessible to Windows users without WSL or admin rights.

Subject: [PATCH 2/2] Update MSYS2 job in GitHub Actions workflow

- Remove unavailable mingw-w64-x86_64-openmpi package
- Disable MPI in CMake configuration

This change allows the MSYS2 Mingw-w64 build to proceed without
errors, though it disables MPI support. Future work may be needed
to re-enable MPI using an alternative package or build method.
