[text-box-trim] Rename text-box-edge values
This patch renames text-box-edge values from:
text-box-edge: leading | <text-edge>
to:
text-box-edge: auto | <text-edge>
Note the <text-edge> definition is unchanged.
<text-edge> = [ text | cap | ex ] [ text | alphabetic ]?
as per the resolution at:
w3c/csswg-drafts#10675 (comment)
and the new spec at:
https://drafts.csswg.org/css-inline-3/#propdef-text-box-edge
As per the new spec, the new auto value is identical to
text when the line-fit-edge property is initial.
The functionality the leading value provided is removed.
