[cmake] CPMUtil: formatting, git_host, new repos, more system deps, libusb (#392)

I promise I'm a UI developer

- mbedtls can now be used as a system package
- zycore can now be used as a system package
- cleaned up dynarmic externals
- fixed libusb incorrectly showing as bundled
- add version/tag formatting to JSON
- add custom GIT_HOST option for packages
- moved some of my repos to my new git
- slightly better version identification
- combined VUL/VH since they are codependent (using my combo vendor)
- fix cpmfile inclusion
- remove libusb submodule

This PR succeeds #383 since it includes it
