Remove text-* properties that never had StyleBuilder support

This patch removes the following 12 properties (listed with usage data):
text-line-through-color: <=0.0001%
text-line-through-mode: 0.0005%
text-line-through-style: 0.0002%
text-line-through-width: 0.0002%
text-overline-color: <=0.0001%
text-overline-mode: <=0.0001%
text-overline-style: <=0.0001%
text-overline-width: <=0.0001%
text-underline-color: 0.0013%
text-underline-mode: <=0.0001%
text-underline-style: 0.0079%
text-underline-width: <=0.0001%

As far as I can tell, these properties have never had any work done on
them since parsing for them was added (trac.webkit.org/changeset/7477).
They were originally defined in CR-css3-text-20030514, but were removed
in WD-css3-text-20050627. Note that the shorthands for these properties
were already removed a year ago in crrev.com/15530002.
