Add 32-bit builds to the workflow

[otavepto]

This PR does the following

• Add x32 and x64 builds for Linux & Windows
• Allow manually triggering the workflow from Actions tab, helpful in debugging the script itself, also could be used exclusively instead of the on push event altogether to save resources if needed
• Update actions/checkout to v4 to solve the workflow nag
• Fix a CMake nag because the required minimum version must be added before project definition
• Make the CMake builds verbose, really helpful for looking into args passed to compiler/linker especially when dealing with different ones

Currently tests cannot build on Linux & Windows, but the project actually works on 32-bit Windows (at least for DirectX). I didn't look into how to solve that.

Please feel completely free to close/reject this if not needed.

Partial implementation for #35
