[tvOS] Use ChannelPosix in Mojo

Browse Source 
tvOS does not support the mach_msg() system API because it lacks
multi-process support. As a result, the tvOS port cannot use
channel_mac.cc, which relies on mach_msg() for interprocess
communication. Instead, it uses channel_posix.cc and channel_posix.h by
disabling `mojo_use_apple_channel`.
