Description
The overhead of HrefPrnFieldMixin is surprisingly high, being actually significant (10-20%) of the total time required during uploading of RPM packages using the synchronous APIs, and perhaps in other circumstances also.
First noted in a prior PR: https://github.com/pulp/pulpcore/pull/6693#issuecomment-2988710298

Research direction
Start with pulpcore/app/serializers/base.py at lines 66-80 and review the prior discussion in pull request 6693. Profile synchronous RPM package uploads to confirm the 10–20% overhead attributed to HrefPrnFieldMixin and identify where its cost occurs. Done means a measured reduction in overhead with the relevant behavior preserved.
