[core] replace #if !OPENTHREAD_RADIO with explicit FTD or MTD check (#11190)

This commit replaces the `#if !OPENTHREAD_RADIO` checks with explicit
`#if OPENTHREAD_FTD || OPENTHREAD_MTD` checks.

The existing check relied on the assumption that exactly one of the
three options `FTD`, `MTD`, or `RADIO` will be set, and therefore
`#if !RADIO`  was used indirectly as a check for `FTD` or `MTD`. This
change improves clarity and allows for future addition of new
configurations (where this assumption may no longer hold true).
