[Fleet] Create intermediate objects when using dynamic mappings (#169981

)

For `dynamic: "runtime"`, and possibly other configurations different to
`dynamic: true`, intermediate objects need to exist for dynamic
mappings, otherwise ingestion can fail with `Missing intermediate object`
errors.

This pull request includes these intermediate objects, and avoids the
creation of static properties with wildcards, that is probably not what
is expected for these mappings.

Intermediate objects are included as static properties for parts of the
name before the wildcard, and as dynamic templates when the full path
has wildcards.

In the modified test files are examples of all of these.

This is more an issue since the following recent fixes, that create the
actual dynamic mappings for some cases where only empty objects were
created before.
