Remove deprecated elements from AudioPage

There are still many elements remaining from the old input system.
These have not been removed due to time constraints. They should
be removed as part of a general clean up process.

The PTT profile buttons have been replaced with a text telling users
to use the SteamVR bindings interface. This is for people who don't
read changelogs.
