Rename position-anchor:implicit to position-anchor:auto
This was resolved here:
w3c/csswg-drafts#10312 (comment)
and will be added to the spec shortly.
This is observable, but barely. After this CL, implicit won't be a
valid value for position-anchor, so it'll resolve to the default
value of auto. Meaning the behavior will be the same. But via the
CSSOM, getComputedStyle(element).positionAnchor will now return "auto"
instead of "implicit".
