[Profiling] Don't map new fields by default (#96876)

With this commit we set the mapping parameter `dynamic` to `false` for
all profiling-related indices / index templates. Previously we were
relying on the default behavior which would have mapped new fields
dynamically. This is problematic for schema evolution. With this change
we will still accept documents with additional fields but they will not
be automatically added to the mappings.
