Revert "Revert "[css3-text]  Implement text-decoration property shorthand""

There was an assertion in StyleResolver caused by the lack of runtime
features check in CSS shorthands style that prevented proper
content_shell usage.

This is now fixed in revision 155866:
https://src.chromium.org/viewvc/blink?revision=155866&view=revision

BUG=165462
Committed: https://src.chromium.org/viewvc/blink?view=rev&revision=155895

What's changed from previous landed patch:

- Added 'runtimeEnabledShorthand' value for text-decoration in CSSShorthands.in
- Rebased against revision 155788 (Replace error-prone value with check from
CSSProperty)

- Skipped getComputedStyle tests for shorthand property, as it is now dependent
on runtime feature check which is disabled by default when running layout tests.

Assuming this change was tested in debug - *hum, hum* - lgtm.

I would have preferred to reopen the original bug to reland the change but that
shouldn't slow you down.
