manifest: bsim: Do not import but keep copy in submanifests/

Due to a limitation in the west import feature,
a project cannot both have an import and be part of a group.
Moreover, when a project has an import and is not filtered
out, it is required for that project to be present
for most west commands to work.

As the bsim project is not filtered by default,
it causes trouble for users who never run a
west update but try to use west further.

To work around this issue, let's disable the import
in the bsim project, and instead copy its manifest
into the submanifests/ folder.

Having a replica of the babblesim manifes in the submanifest
folder is likely to cause some confusion in users,
wrt to which version of components they are using.
So whenever west supports both imports and groups, or another
simple and nicer way of working around this, it should be used.
