Xcode: Add source file property to control file type (#14854)

Add source file properties to control Xcode file type attributes:

  XCODE_EXPLICIT_FILE_TYPE   => explicitFileType
  XCODE_LAST_KNOWN_FILE_TYPE => lastKnownFileType

Add a RunCMake.XcodeProject test to verify generated project content.
