serial: introduce SERIAL_SUPPORT_INTERRUPT Kconfig option

Browse source 
As not all drivers support interrupts we don't have a means to know if
we can allow UART_INTERRUPT_DRIVEN to be enabled and thus various
Kconfig options that select UART_INTERRUPT_DRIVEN.  Some drivers have a
interrupts, however not all do.  So introduce a Kconfig option to let us
know what the driver actually supports.
