native_posix is now deprecated.
Building these tests in both native_sim and native_posix does not
improve coverage for the tests or subsystem but doubles CI time.
As anyhow native_posix will be removed all together in
2 releases, let's remove it already for these.

For the 64 bit targets, change identifiers to the new hwmv2 ones.
And remove redundant overlays (which were equal for the 32
and 64 bit versions)
