Use WriteOrBufferDataAtLevel to send crypto data. Such that existing WriteOrBufferData is used to send application data.

Change SendHandshakeMessage to take encryption level instead of using current default encryption level.

Protected by FLAGS_quic_reloadable_flag_quic_use_write_or_buffer_data_at_level.
