Stop duplicating projections of type annotation.
This commit changes how type annotations are handled in bindings during MIR building. Instead of building up a `PatternTypeProjections` with the `CanonicalUserTypeAnnotation` and projections, the `CanonicalUserTypeAnnotation` is stored in the `canonical_user_type_annotations` map at the start and the (equivalent) `UserTypeProjections` is built up with the new index and same projections. This has the effect of deduplicating type annotations as instead of type annotations being added to the `canonical_user_type_annotations` map multiple times at the end after being duplicated (which happens in building up `PatternTypeProjections`), it is instead added once.
