Update LayoutTests scripts to skip webgl folder on ports

I'm working on checking in the WebGL Conformance Tests
as layout tests into LayoutTests/webgl. For ports
that do not have WebGL enabled this changes will
skip tests in the "webgl" folder.

Web Inspector: fix "DOM Exception 8" when deleting lines containing decoration in DTE.

Add a check that decoration element is still added to the line before trying to delete it. This
won't be true if the whole line is deleted in contentEditable,
and this is the reason for the exception to be thrown.

No new tests.
