feat: Add service request history for asset

[Ashesh3]

Required for: ohcnetwork/care_fe#5363
This pull request adds a new AssetService model to the project, which will allow us to store all records of service requests for each asset. This pull request also introduces an AssetService serializer in the care/facility/api/serializers/asset.py file. The AssetService serializer is used to retrieve the last service of an Asset. In the AssetSerializer serializer, last_service is added as a read-only field, and last_serviced_on and note are added as write-only fields. The last_service field retrieves the last service of the Asset using the AssetService serializer.

This pull request also includes changes to the create and update methods of the AssetSerializer serializer to save the last_service data when an Asset is created or updated. The AssetServiceFilter filter is also added to the care/facility/api/viewsets/asset.py file to filter Assets by external id.

Migration has been created to move existing service request to a new AssetService object linked to that asset.
