stm32: uart: add USART_FLAG_ defines
Similar to how we have abstract defines for the stop bits, parity and
flow control common mode namees, provide abstract flag names for the
"standard" flags. This allows us to start using common API code for v1
and v2 uarts
For stm32f3, drop the "compatibility" defines that simply pollute the
namespace, making it confusingly appear as if f3 has both SR and ISR
registers.
