twister: add flash-before option

Browse source 
Add option to flash board before attach serial.

Current implementation performs the following sequence:

1. Open serial port to listen to board log output
2. Flash device

In case of ESP32 where it uses the same serial port
for both operations, flashing needs to come first.

This PR adds a twister option named --flash-before
which enables the process above, allowing tests to be
performed properly.
