BaseTools/Scripts/PatchCheck.py: Check for Change-id

Code review tools like gerrit might use a 'Change-id' tag to track
the evolution of patches. This tag should be removed before
submitting a patch to the mailing-list.
It has been observed that contributors sometimes forget to remove
this tag. Add a check in PatchCheck.py to automate this.

Also add a '--ignore-change-id' command line parameter to ignore
the above check.
