Make <option> and <optgroup> share a text content algorithm
https://bugs.webkit.org/show_bug.cgi?id=324223
Reviewed by Tim Nguyen.
Implements https://github.com/whatwg/html/pull/12232, which replaces
"collect option text" with "get HTML-aware text content", now shared
between <option> and <optgroup>.
Getting an <optgroup>'s label now only considers a <legend> that is the
optgroup's first element child, falling back to the label attribute and
then the empty string.
The label element has to look like a <legend>, which is the entire
reason it exists, so it now shares their user agent style rule through
an -internal-optgroup-label user agent part rather than carrying two
inline padding properties that had drifted from that rule.
fast/forms/select/optgroup-option-shadow-tree.html expected the label
element to exist only for a label attribute, so update it, and cover a
<legend> that is not the first element child while there.
The reference tests are not always passing due to the slight shift of the
picker icon as noted in TestExpectations.
