applet.interface.uart: don't silently drop frames on overflow.

Partial fix for #263.

applet.interface.spi_controller: add stub mode parameter.

This parameter is currently just there to make any downstream user
stop and consider whether their device actually uses Mode 3 or not.
Once SPI modes are implemented properly, it will configure the SPI
controller.

gateware.{spi,qspi}: fix to actually comply with Mode 3.

Before this commit, the clock would idle low after the first transaction
was completed.

applet: be explicit if pin is required or optional.

Many applets have optional pin arguments for some auxiliary function,
but this is currently non-discoverable if they have a default value,
since they look exactly the same as a required argument.

applet.interface.spi_controller: make COPI/CIPO optional.
