QuicConnection methods call CloseConnection rather than
TearDownLocalConnectionState

Some of the QuicConnection methods call TearDownLocalConnectionState
rather than CloseConnection. This changes then all to call CloseConnection,
specifying ConnectionCloseBehavior::SILENT_CLOSE.

Some tests modified to expect calls to CloseConnection (preventing test failure due to unexpected calls).  Before this CL the connection closing happened via internal calls directly to TearDownLocalConnectionState; now these calls go through CloseConnection and trigger the expect.

This is done in preparation for landing another CL adding IETF QUIC Connection Close functionality.

QuicConnection::OnUnrecoverableError (which is an override of QuicPacketCreator::OnUnrecoverableError) called TearDownLocalConnectionState. It had to be modified to call CloseConnection.  OnUnrecoverableError has a ConnectionCloseSource parameter, which CloseConnection does not take.  Thus the parameter was removed from OnUnrecoverableError.  This is OK since all of the calls to OnUnrecoverableError specified FROM_SELF as the source. CloseConnection uses FROM_SELF as the source (unless the error code is a stateless reject or public reset).

gfe-relnote: No flag protection as it is only moving existing functionality around.
