LibIPC+Everywhere: Change IPC::encode's return type to ErrorOr

Browse Source 
In doing so, this removes all uses of the Encoder's stream operator,
except for where it is currently still used in the generated IPC code.
So the stream operator currently discards any errors, which is the
existing behavior. A subsequent commit will propagate the errors.
