Compile with `clang-cl`

Currently not working. The quickest way for you to have a glimpse at this appending `/p:CLToolExe="clang-cl.exe"` to the MSBuild command on https://github.com/SpartanJ/eepp/blob/develop/.github/workflows/eepp-windows-build-check.yml. It seems Premake has support for targeting `clang-cl` at the `premake5.lua` level. But I'm basically illiterate on Premake build script. The log is too large. We need to suppress the unnecessary warnings before we can focus on the actual compilation errors.
