[ty] Clean up inherited generic contexts (#20647)
We add an `inherited_generic_context` to the constructors of a generic
class. That lets us infer specializations of the class when invoking the
constructor. The constructor might itself be generic, in which case we
have to merge the list of typevars that we are willing to infer in the
constructor call.

Before we did that by tracking the two (and their specializations)
separately, with distinct `Option` fields/parameters. This PR updates
our call binding logic such that any given function call has _one_
optional generic context that we're willing to infer a specialization
for. If needed, we use the existing `GenericContext::merge` method to
create a new combined generic context for when the class and constructor
are both generic. This simplifies the call binding code considerably,
and is no more complex in the constructor call logic.

We also have a heuristic that we will promote any literals in the
specialized types of a generic class, but we don't promote literals in
the specialized types of the function itself. To handle this, we now
track this `should_promote_literals` property within `GenericContext`.
And moreover, we track this separately for each typevar, instead of a
single property for the generic context as a whole, so that we can
correctly merge the generic context of a constructor method (where the
option should be `false`) with the inherited generic context of its
containing class (where the option should be `true`).
