Part of JSON primitive collection serialization

[ajcvickers]

Part of #30677

There is still work to do here, but this is basically working so I wanted to get it out for review.

Remaining work:

• Negative cases/exception messages
• Re-introduce checks for whether or not query supports primitive collections
• Cases where the primitive collection object exists and should be added to
• Custom element type mapping on the property
• Custom element reader/writer
• Custom collection reader/writer
• Use default element type mapping configured in ConfigureConventions
• Update Cosmos primitive collection mapping
• More query tests!
