The CSSWG resolved in https://github.com/w3c/csswg-drafts/issues/4568
that inherited properties that apply to text can be set on ::marker and
should affect the marker text.

Therefore, this patch allows text-decoration-skip-ink, text-emphasis,
-webkit-text-emphasis-color, -webkit-text-emphasis-position,
-webkit-text-emphasis-style, and text-shadow in ::marker.

text-underline-position is not allowed despite being inherited because
it doesn't affect underlines specified by ancestor elements. And since
text-decoration-line is not allowed, it would be pointless.

Bug: 1031667

TEST=external/wpt/css/css-pseudo/marker-text-decoration-skip-ink.html
TEST=external/wpt/css/css-pseudo/marker-text-emphasis.html
TEST=external/wpt/css/css-pseudo/marker-text-shadow.html
TEST=external/wpt/css/css-pseudo/parsing/marker-supported-properties-in-animation.html
TEST=external/wpt/css/css-pseudo/parsing/marker-supported-properties.html

Some parsing tests fail because unprefixed text-emphasis hasn't been
implemented. And some reftests fail in legacy because ::markers with
'content: normal' are not implemented using actual text.
