Feature Request: Ability to change bluetooth device name from SerialBT

[abdukir]

Been using the SerialBT library for a while, ESP's implementation can pass the desired device name with SerialBT.begin(device_name). Currently i'm changing the line below in SerialBT.cpp manually. It'd be great to have similar functionality

arduino-pico/libraries/SerialBT/src/SerialBT.cpp

Line 79 in 679be85

gap_set_local_name("PicoW Serial 00:00:00:00:00:00");
