Reviewed by Chris Fleizach.

Tools:

Move the platformName property from the testRunner into
accessibilityController, since this is a concept that has only be
used by accessibility tests since it got added, and also because
the real intention was not to distinguish among "ports" (mac, win,
gtk, efl) but between platforms (atk, mac, win).

This change will be very useful to merge GTK's roles-exposed.html
and Mac's role-subrole-roledescription.html into one single test,
since we will be specifying in the test itself which elements are
supported in which accessibility "platform". In this context,
being able to check accessibilityController.platformName directly
against a list of supported accessibility platforms (e.g. "atk,mac")
will certainly maintain the code cleaner and simpler.
