Two resources with one properties flattens while the other not

[pshao25]

HybridConnectivity has two resources:

1. ServiceConfigurationResource with "x-ms-client-flatten": true.
2. EndpointResource with "x-ms-client-flatten": false

How could we represent these two in same spec?

@pshao25 This feels like a tcgc issue. flattening is strictly client-specific and has no impact on the actual API. The agreement was for flattening to be enabled or disabled for a spec - since this only impacts clients, if more granular control over flattening is required, these seem to belong to client-side decoration
