[css-ui] Fix all current bikeshed warnings

Looks good except for the changes:

from: <a spec="css-style-attr">style attribute</a>

to: <a href="http://dev.w3.org/csswg/css-style-attr/#style-attribute">style attribute</a>

What is the reason NOT to use spec="css-style-attr"?
And we should not be directly linking to dev.w3.org draft URLs as references (will block us from advancing to CR).

Rather than using absolute URLs to avoid Bikeshed warnings, you can update the linking defaults to select the proper specs:
https://github.com/tabatkins/bikeshed/blob/master/docs/definitions-autolinks.md#configuring-linking-defaults

Then Bikeshed should choose the /TR versions of the specs when generating for /TR.

[frivoal]

The problem with style attribute is that the the css-style-attr spec defines the term multiple times, so if we let bikeshed auto-link, even if we point it to the right spec, it will complain that it's ambiguous. The bug is in css-style-attr, not in css-ui, but I wanted to work around it to get to 0 warnings.

Since it is a REC already (and therefore is unlikely to change any time soon), I'll just link to TR instead.

[frivoal]

Link updated.

[tabatkins]

If it defines the term multiple times, it's definitely a bug, but also it's probably okay for any of them to be the link target. To just shut Bikeshed up about the error, put it in an "Ignored Terms" metadata; that way it'll silently choose the first dfn in its database without emitting a warning.

[frivoal]

I thought "Ignored Terms" meant it wouldn't link at all. At least that's what the here doc claims:
https://github.com/tabatkins/bikeshed/blob/master/docs/metadata.md

[tabatkins]

Whoops, ignore that documentation while I correct it. All Ignored Terms does is silence the warnings/errors from autolinking that term.

Hard-linking to the w3.org/TR drafts is a reasonable path forward for those references.
