samples|tests several: Support using nrf5340bsim hwmv2 names

For all samples which handle the nrf5340bsim in some special way
(for example in sysbuild files, or by checking what samples are
supported) handle also building with the hwmv2 names.

Also, let's fix the cmake info message in these respective
samples which tells the user which board target is used for which
part of the app.
