Jonathan Nilsen d403d73ad7 boards: nordic: update custom JLink reset scheme for ADACv2
Version 2 of the ADAC interface implemented by secure domain firmware
changes the ADAC RESET command used in the custom reset handling in
the JLink support scripts. The command has been split into two
commands, RESET and START, and has different semantics from
the previous RESET command. The new RESET command resets both the
application and radio domains without starting the CPUs again, and the
START command must then be used to start the CPUs.

Update the JLink support scripts for nrf54h20dk/nrf54h20/cpuapp,
nrf54h20dk/nrf54h20/cpurad, nrf9280pdk/nrf9280/cpuapp and
nrf9280pdk/nrf9280/cpurad so that they read out the ADAC interface
version from the device and use the newer commands if ADAC version 2 is
detected. If the version is lower than 2, the legacy implementation is
used.

Also improve the CTRL-AP MAILBOX transaction implementation
to avoid the need for arbitrary sleeps or unnecessary polling of
the MAILBOX. This should improve stability when using the script.
