extmod/modbluetooth: Persist reference to NimBLE service instances.

Browse Source 
NimBLE doesn't actually copy this data, it requires it to stay live.
Only dereference when we register a new set of services.

Fixes #5226

This will allow incrementally adding services in the future, so
rename `reset` to `append` to make it clearer.
