Close log build date, git branch and commit hash, #3970

Updated to address review comments.

This commit will:
- Add custom keys to Info.plist to contain build information
- Enable preprocessing of the Info.plist file in the Xcode build
- Enable use of an Info.plist header file in the Xcode build
- Add a shell script write_info_plist_header.sh that generates the
  Info.plist header file
- Add a new Xcode build phase to execute the script
- Add a new logBuildDetails method to AppDelegate

With these changes IINA will log a message during startup containing the
build date, git branch and commit hash.
