Add UART9/10 support.

Browse source 
* UART9 was supported as LPUART on some H7s.
* Newer 100-pin H7 CPUs support UART9 and USART10.
* 100+ pin devices support higher numbered UARTS than UART10.

Use USE_LPUART instead of hacking into UART9 for clarity.

* LPUARTS are different from other types of UARTS.
* They need different ID ranges.
* They have and different capabilities.
* Renumber LPUART1 to 40.

0-19 reserved for UART1-20
40-49 onwards for LPUART instances.

It makes sense to treat them as a different class of UART.  Just like we
do for softserial, vcp, etc.
