Log Message:
-----------
Allow negative length values for overflow-clip-margin property
https://bugs.webkit.org/show_bug.cgi?id=323162
Reviewed by Sam Weinig and Tim Nguyen.
In [1], CSSWG resolved that overflow-clip-margin also applies to
scrollable boxes and can take negative length values. Change the
CSS property definition, parser function and style value to allow
all length values. Layout and rendering code does not use the
property yet, so no changes needed there.

Added new test cases in existing tests.
