Set up MinGW-w64

This is a GitHub action that sets up MinGW-w64 in your workflow run.

Use it in your workflow like this:

- name: Set up MinGW
  uses: egor-tensin/setup-mingw@v2
  with:
    platform: x64

x64 is the default value for the platform parameter and can be omitted. Use x86 if you want to build 32-bit binaries.
Set the cygwin parameter to 1 to set up MinGW inside an existing Cygwin installation (see my other action for setting up Cygwin itself).
cc and c++ executables are set up, pointing to the *-gcc and *-g++ executables. Disable this by setting the cc parameter to 0.
