hci_uart_async/debug.mixin.conf is used to enable RTT logging
for hci_uart_async sample. RTT can be used to avoid conflict
between different serial interfaces because the sample uses
UART as an interface for HCI communication.
RTT_CONSOLE option enabled in the debug.mixin.conf depends on
CONFIG_USE_SEGGER_RTT so enabling CONFIG_USE_SEGGER_RTT by
default makes it easier to build the project with RTT enabled

This sample is an alternative implementation of hci_uart. The new sample
differs from the existing sample in that it uses the async UART API
instead of the interrupt driven API.
Included in this commit is a new test for HCI UART flow control. It's
enabled for hci_uart_async. The test can excercise also the existing
hci_uart sample (with some minimal changes to allow compiling in the
mock controller and test suite). The existing hci_uart sample currently
fails the flow control test.
