[TCGC] Constant type with the same value in different context should have different generated names

Like anonymous models, constant type in different places should have different generated names because downstream SDKs would like to model them as different types to avoid future breaking changes.

In this playground, we have two models `Foo` and `Bar`. They have a property `kind`, with the value of `"kind"`.
But in the type graph, they have the same generated name as `FooKind`.

Start by reproducing the linked Playground example with the two models, Foo and Bar, and inspect their type-graph entries for the kind properties. Trace how the shared value "kind" becomes the generated name FooKind; done means equivalent constant types in different contexts receive distinct generated names so downstream SDKs can model them separately.
