4a06e21bf9 RequirementMachine: Introduce rules for protocol typealiases from requirement signatures 
When building a rewrite system for a generic signature or protocol,
we would add requirements from the requirement signature of every
protocol dependency. Now, also add protocol typealias rules as well.

a1c03db381 AST: Generalize ProtocolDecl::getRequirementSignature() to a new RequirementSignature type 
The RequirementSignature generalizes the old ArrayRef<Requirement>
which stores the minimal requirements that a conforming type's
witnesses must satisfy, to also record the protocol typealiases
defined in the protocol.

c58d9d8974 Sema: StructuralRequirementsRequest collects protocol typealiases 
Introduces rewrite rules for typealiases defined inside the protocol
itself.

Typealiases defined in protocol extensions do not participate
in the rewrite system, except for when they have the same name as
an associated type, as per the weird rule codified in the
TypeAliasRequirementsRequest for GSB compatibility.

28c1178c4f RequirementMachine: Introduce TypeAliasRequirementsRequest 
This is a verbatim copy of the GenericSignatureBuilder's somewhat
questionable (but necessary for source compatibility) logic where
protocol typealiases with the same name as some other associated
type imply a same-type requirement.

The related diagnostics are there too, but only emitted when
-requirement-machine-protocol-signatures=on; in 'verify' mode,
the GSB will emit the same diagnostics.
