Expose accessibility config on PhoneInterfaceManager.

+ Add methods to PhoneInterfaceManager, so that elsewhere in the
system applications can tell whether TTY mode or HAC are supported
by querying the TelephonyManager.
+ Updated some usages/exposure of configs in Telephony.
+ Some styling/capitalization fixes.
