feat(schema): de-dupe re-used fields in the descriptor

[judofyr]

Description

This changes the format of the schema descriptor (i.e. the server-side schema) to automatically detect when a field or array member is reused and then hoists it outside as a separate object.

What to review

• That the overall algorithm makes sense and is correct. This shouldn't touch anything outside of the schema descriptor stuff.

Testing

• I should probably add a unit test for the behavior here. I can look into that.

Notes for release

N/A. Still only internal.
