Bluetooth: hci_uart: Provide generic H:4 receive framework

Browse Source 
Future H:4 based UART drivers require custom packet types and custom
receive functions. To support this, extended the h4_recv_buf function
with a packet definition table.

For the default H:4 packets types of ACL data, SCO data and events,
provide helpers to reduce the amount of code duplication.
