Merge CSSProperties.in and CSSShorthands.in

This patch is part 1 of merging the CSS .in files (part 2 is also up, at
https://codereview.chromium.org/415613002). Having a single .in file for
listing CSS properties makes it both easier to add new properties and
add new property flags.

I've renamed some of the StyleBuilder flags to make it more obvious what
these refer to and also re-ordered CSSProperties.in in some sort of
sensible fashion (see part 2 patch for what this will look like with the
remaining properties); the high/low priority split doesn't make too much
sense right now but will of course make sense once CSSPropertyNames.in
is merged into the same file.

Have DocumentOrderedMap API deal with AtomicString type instead of StringImpl*

Have DocumentOrderedMap API deal with AtomicString type instead of StringImpl*
as it would be unsafe to use if the StringImpls were not atomized.

This basically moves the AtomicString::impl() calls from the DocumentOrderedMap
API call sites to the DocumentOrderedMap implementation. This simplifies the
call sites a bit and makes the DocumentOrderedMap code look safer.

Oilpan: RenderMenuList should call PopupMenu::disconnectClient in destroy().

PopupMenu::disconnectClient accesses some objects, and they might be destructed
when a RenderMenuList object is garbage collected. We should call
PopupMenu::disconnectClient earlier.

This fixes SelectPopupMenuStyleTest.PopupListBoxRTLRowWidth in Oilpan.
