samd/machine_uart: Add full support for 9-bit data.
Prior to this commit, 9-bit UART data could be specified in the constructor
and was transmitted, but the 9th bit was set to 0 when sending, and ignored
when receiving. This commit completes 9-bit support in that the 9th bit is
taken from the data.
9-bit data has to be provided with `uart.write()` and and read with
`uart.read()` as two bytes for each transmitted item, low order byte first.
The data length supplied with `uart.write()` and requested by `uart.read()`
has to be even, which is checked. The size of the UART buffers will be
transparently doubled to cater for 9-bit data.
