This patch is to align WebKit with Blink / Chromium, Gecko / Firefox and Web-Specifications.

Inspired - https://chromium.googlesource.com/chromium/blink/+/278d9993a71dfaa8f8e324ac021313ea038e5e44

This patch is to remove 'bgproperties", which was supported by Internet Explorer but not by Gecko
and never standardized.
Blink also removed it in 2014 and now only WebKit / Safari support it and this patch is to remove last
usage and align all browser engines.

* Source/WebCore/html/HTMLAttributeNames.in: Remove 'bgproperties'
* Source/WebCore/html/HTMLBodyElement.cpp:
(HTMLBodyElement::hasPresentationalHintsForAttribute): Remove 'bgpropertiesAttr'
(HTMLBodyElement::collectPresentationalHintsForAttribute): Ditto
