Adds a basic uart service which can act a host service when eSPI is not available. Still uses the SmbusEspiMedium even though the SMBUS header isn't necessary just to keep code changes on the host side minimal when switching between UART/ESPI.

Did some testing on the IMXRT board and can send/receive MCTP packets from host over a COM port successfully. Might catch additional bugs as I work on getting the ratatui app working over UART and will fix them as they come.

Resolves #605
