[ty] Track different uses of legacy typevars, including context when rendering typevars (#19604)
This PR introduces a few related changes:

- We now keep track of each time a legacy typevar is bound in a
different generic context (e.g. class, function), and internally create
a new `TypeVarInstance` for each usage. This means the rest of the code
can now assume that salsa-equivalent `TypeVarInstance`s refer to the
same typevar, even taking into account that legacy typevars can be used
more than once.

- We also go ahead and track the binding context of PEP 695 typevars.
That's _much_ easier to track since we have the binding context right
there during type inference.

- With that in place, we can now include the name of the binding context
when rendering typevars (e.g. `T@f` instead of `T`)
