tint/writer: Replace scope_stack_, fix type ctor scoping.

ScopeStack is not needed here - the resolver already provides variable scoping with the sem::Variables.

Re-purpose scope_stack_ for a stack of Scope, which now holds the type constructor -> SPIR-V ID map.
This map needs to be per-scope, to fix issues like crbug.com/tint/1520

Fixed: tint:1520
