Add use counters for a number of extensions and non-standard APIs

Add use counters for a number of extensions and non-standard APIs

Found by searching for "extension" and "non-standard" in *.idl.

Some APIs which are documented as extension/non-standard in the IDL are
now standardized, and no counters were added for those, like
Document.readyState.

Ad-hoc testing was done in Firefox and IE. It looks like the comments
about IE/Mozilla/WebKit extensions are mostly accurate, and none of the
touched APIs are implemented in both Firefox and IE.

We don't have a way in the bindings generator to say that "foo" should just call
"getAttribute("foo")", "setAttribute("foo")"?

It does call getAttribute() - or rather fastGetAttribute() - and setAttribute(),
and in simple cases that's basically all it does.
See v8_attributes.py - specifically getter_base_name() and setter_base_name().

Can also see output in V8TestObject.cpp (test cases in TestObject.idl), by
searching for getattribute and setattribute:

i see, I thought this was HTMLPreElement::parseAttribute, which is why I asked
the question nbarth answered.  I see now this is really a separatge countable
path.
