Remove all support for the Carbon NPAPI event model

Remove all support for the Carbon NPAPI event model

Plugins already cannot negotiate the Carbon event model; this removes
all the code supporting the Carbon model now that it is no longer
necessary.

The interpose library is left in place because plugins that use the
Cocoa event model may still make Carbon OS calls for window or cursor
managament.

Note that I don't actually think we should keep supporting the Carbon cursor
interposing, since any plugin needing cursor support should switch to Cocoa. I'm
going to do that as a separate CL though, since it's conceptually unrelated to
this.
