.github: Initial Github Actions

- Based on:
https://github.com/RPCS3/rpcs3/tree/master/.github/workflows
https://github.com/Caio99BR/pkgi-ps3-nopaystation/tree/main/.github/workflows

- Currently building only for Ubuntu x64, Windows (intel32 and x86_64) and Aarch64

- SCCache is used as default to speed up subsequent builds (each build takes ~3m, after caching)

- "LLVM/Clang/LLD based mingw-w64 toolchain" (nightly builds) is used as default

- Many improvements can be made for this, as well support for others archs, but this is the initial implementation
