Do not cache device ID salt in MediaDevicesDispatcherHost.

This is the first in a series of CLs to remove caching of the device ID
salt in the following browser objects:
-MediaDevicesDispatcherHost
-MediaStreamDispatcherHost
-AudioRendererHost

The salt can be reset by the user at any time by clearing browsing data.
Caching it leads to using a stale salt, which results in noncompliance
with the spec, which requires user-visible device IDs to be reset when
cookies are cleared.
Furthermore, the objects mentioned above have different lifetimes, which
leads to inconsistencies if a user clears browsing data.

Remove Media Device Salt cache from MediaStreamDispatcherHost

This is part of a series to remove the caching of the Media Device salt
from various browser objects.

This CL replaces the salt cache with use of the
GetMediaDeviceSaltAndOrigin() utility function.

This CL also removes passing the security origin from the renderer
process since it is now obtained with the same utility function.

Remove caching of salt in AudioOutputAuthorizationHandler

The user can reset the salt at any time by clearing browsing data.
Keeping the salt cached can lead to failure to authorize valid device
IDs if the user clears browsing data.

This is the last CL in the series.
