CMake: Update CI

- Duplicated the ci.yml into ci-scons.yml and ci-cmake.yml
- Replaced some manual shell commands to detect changes with  tj-actions/changed-files@v45
- Conditionally run the CI depending on what files change.
- Add ios toolchain from leetal/ios-cmake
- Added a cmake-minimum of 3.10 to silence errors from ios toolchain
