[whatwg] The set of supported @type values for <script> is a bit odd

The list is at 
depending on which you prefer to read.

It seems to include several values that no UA actually supports, 
apparently because of the way the spec uses the same list to deal with 
both @language and @type.  See compat testing data at 
https://bugzilla.mozilla.org/show_bug.cgi?id=672814#c6 and the testcase 
I used to generated that data at 

At the moment our plan in Gecko is to just implement this list as-is, I 
think: it's a superset of what everyone implements, and it just doesn't 
feel worth pushing back on the two Presto-only items and the three "no 
one implements this" items.

This mail is just a heads-up for people in case they want to protest, 
before we go ahead and ship this full list in Gecko.
