[nrf noup] scripts: west_commands: runners: nrf: workarounds for SDFW v8.0.0

SDFW v8.0.0 introduces certain changes that require matching changes
in nrfutil device to ensure that west flash works properly on
nrf54h20dk and nrf9280pdk.

This commit adds a few temporary workarounds to ensure that west flash
works with an older nrfutil device version as well:

1. Don't erase UICR, as this tries to erase the extended UICR regions
   as well, and those regions no longer exist (resulting in an error).

2. Do a RESET_VIA_SECDOM reset before programming firmware. This ensures
   that all the cores are stopped before writing firmware. Removing the
   UICR erase step seemed to cause some instability when programming,
   which is suspected to be caused by the firmware running while
   programming.
