Merge 135829 - :read-only selector should match to date/time input types
https://bugs.webkit.org/show_bug.cgi?id=103350

Reviewed by Kentaro Hara.

Source/WebCore:

We supported :read-only and :read-write only for text form controls;
i.e. <textarea> and text-field <input>. According to [1], we should
support them for date/time types. So, this patch removes
isTextFormControl check in SelectorChecker, and just relies on
shouldMatchRead{Only,Write}Selector virtual functions.

Tests: Update fast/forms/*/*-appearance-pseudo-classes.html.
