west: runners: nrf: Generalize the erase command

Browse source 
Instead of providing an `--erase-pages` command, generalize it to a new
`--erase-mode` one that can be set to `none`, `ranges`, or `all`. This
gives the user full control over the erase mode that will be passed on
to nrfutil.

* All boards based on a Nordic IC of the nRF54L series now default to not
erasing any part of the internal storage when flashing. If you'd like to
revert to the previous default of erasing the pages that will be written to by
the firmware to be flashed you can use the new ``--erase-pages`` command-line
switch when invoking ``west flash``.
the firmware to be flashed you can set the new ``--erase-mode`` command-line
switch when invoking ``west flash`` to ``ranges``.
Note that RRAM on nRF54L devices is not physically paged, and paging is
only artificially provided, with a page size of 4096 bytes, for an easier
transition of nRF52 software to nRF54L devices.
