add url_utils to common repo from skia repo

Once gs_utils.py is moved into common, these would be the only files left in https://skia.googlesource.com/skia/+/master/tools/pyutils/ .  So let's just move them all...

LGTM with the usual copy/paste question.

https://codereview.chromium.org/382933002/diff/1/py/utils/url_utils.py
File py/utils/url_utils.py (right):

https://codereview.chromium.org/382933002/diff/1/py/utils/url_utils.py#newcode1
py/utils/url_utils.py:1: #!/usr/bin/python
Is this a pure copy/paste?

https://codereview.chromium.org/382933002/diff/1/py/utils/url_utils.py#newcode33
py/utils/url_utils.py:33: An Exception, if filepath is already a URL.
Why? Is this ever better than just returning the passed-in filepath?

Yes, both files were pure copy from

I dunno.  Figure I should just leave this as-is for now.
