Change baudrate dynamically through dbus

Create a dbus interface so that user can change baudrate dynamically.
With this feature, SOL can still work correctly when BIOS switch uart
from high speed uart to normal uart.

Tested By:
Run busctl introspect xyz.openbmc_project.console /xyz/openbmc_project/console
the property baudrate show the current baudrate.
Run busctl call xyz.openbmc_project.console /xyz/openbmc_project/console
xyz.openbmc_project.console setBaudRate x 9600
The property baudrate show 9600 now. After change BIOS console redirection
to 9600 baudrate and change putty client also to 9600. SOL and serial port can
work correctly.
