Richard Smith e1c8c1f855 Use specific_constant when referring to name in enclosing generic (#7936) ...

When unqualified lookup finds a name from an enclosing generic, create a
`specific_constant` if it's a constant, or a `specific_inst` otherwise,
to refer to that name from the inner generic. This allows consumers of
generic instructions to always use a specific of the current scope's
generic when accessing the constant value or type of a dependent
instruction.

Fixes crashes in dominance and in `GetExprCategory` caused by using
specifics for the wrong generic.
