Assign a connection to a poll group. Note that a connection may only belong to a
single poll group. Adding a connection to a poll group implicitly removes it from
any other poll group it is in.
You can pass k_HSteamNetPollGroup_Invalid to remove a connection from its current
poll group without adding it to a new poll group.
If there are received messages currently pending on the connection, an attempt
is made to add them to the queue of messages for the poll group in approximately
the order that would have applied if the connection was already part of the poll
group at the time that the messages were received.
Returns false if the connection handle is invalid, or if the poll group handle
is invalid (and not k_HSteamNetPollGroup_Invalid).
