feat: use a different associated field for references on native

[dpilch]

Description of changes

• remove respectReferences and enable references for all platforms
• use the connected field instead of associatedWithFields on native for references

Example:

type Primary @model {                                                                                                                
  tenantId: ID! @primaryKey(sortKeyFields: ["instanceId", "recordId"])                                                               
  instanceId: ID!                                                                                                                    
  recordId: ID!                                                                                                                      
  content: String                                                                                                                    
  related: [Related!] @hasMany(references: ["primaryTenantId", "primaryInstanceId", "primaryRecordId"])                              
}                                                                                                                                    
                                                                                                                                     
type Related @model {                                                                                                                
  content: String                                                                                                                    
  primaryTenantId: ID!                                                                                                               
  primaryInstanceId: ID!                                                                                                             
  primaryRecordId: ID!                                                                                                               
  primary: Primary @belongsTo(references: ["primaryTenantId", "primaryInstanceId", "primaryRecordId"])                               
}  

The .hasMany on the generated model for native platforms will use associatedWith: primary instead of associatedWith: ["primaryTenantId", "primaryInstanceId", "primaryRecordId"]. This is how composite primary keys work for native currently.

naming nit, otherwise LGTM

[palpatim]

naming nit: can we come up with something more descriptive than V2? :) Maybe getConnectedFieldForNativeReferences or something?

[phani-srikar]

Looks like the getConnectedFieldV2 API was around for a while and used in multiple places. We can maybe refactor this outside of this PR?

I moved the refactor to #822
