Removal of old runner options caused downstream breakage

[mbolivar-nordic]

Describe the bug

Commit 2cee5ff ("scripts: west_commands: runners: remove deprecated options") was merged without the maintainer's approval and subsequently broke at least one known environment where the removed options were still in use.

Although that reported breakage was worked around via other means, the possibility remains open that other workflows which used these options have regressed and no longer work.

To Reproduce
Steps to reproduce the behavior:

1. git checkout 2cee5ff
2. west update
3. west build -b nrf52840dk_nrf52840 samples/hello_world
4. west flash --snr <your_board_snr>
5. bzzt

Expected behavior

We should, whenever it is practical and does not cause undue maintenance burden, maintain backwards compatibility with older runner command line options to avoid breaking automated workflows using these options.
