pac modelbuilder - Use DisplayName for BPFs

By default, the naming service for bpfs uses the logical names, not the display names. This generates some extremely hard to read names in the format Publisher_bpf_GUID. The Display Name should be used instead (and the GUID can be added if there is a duplicate name)

If it's helpful, I've added code to my naming service to resolve this in the EarlyBound Generator
https://github.com/daryllabar/DLaB.Xrm.XrmToolBoxTools/commit/bc5b43b0105b4aac5ec06c1057186ef48a3ec1d8#diff-64f3542665f7570012cb548d669a5aa4593bb81515364f402cc8156fa88cec81 (look at the GetNameForEntity method particularly, although I'm assuming that there is a better way to determine that the entity name is for a BPF entity)

Also for relationship names:
https://github.com/daryllabar/DLaB.Xrm.XrmToolBoxTools/commit/4dfd96164b0626947bd07eb5017b01c2d4bfd9e2#diff-64f3542665f7570012cb548d669a5aa4593bb81515364f402cc8156fa88cec81 (look at GetNameForRelationship method)

Locate the PAC ModelBuilder naming-service or BPF model-generation entry point, then compare its behavior with the referenced GetNameForEntity and GetNameForRelationship examples. Done means BPF names use DisplayName values, append a GUID only for duplicates, and relationship names follow the intended naming behavior.
