Fix

- Add WIP HidNX Driver (clangd not working with devkitpro for switch on windows)
- Add default-release as default search path for compile_commands.json
- remove mingw preset (casue its exactly the default target)
- Move Mouse pos cycle into HidDriver::Update
- Test around with HidGlfw on Nintendo switch
