Support renamed errors in aws-json-1.1 protocol

[everett1992]

Describe the feature

Smithy recently allowed renaming error shapes but added a validator to prevent renamed errors with aws protocols.

Most aws protocols only use shape name in error serialization, which is why error renames were originally banned. However, aws json 1.0 uses qualified shape id and can support renamed errors.

The protocol should match errors based on the original (not renamed) fully qualified shape id.

Once all smithy sdk's (rust, js, go, kotlin) confirm that aws json 1.0 supports renamed errors smithy can remove the protocol from the validator and allow renames.

smithy-lang/smithy#1545

Use Case

I have smithy a smithy model with shapes with conflicting names, tho the qualified shape id is unique. I'd like to use aws json 1.0 protocol, which could support renamed error shapes, but the validator throws an error.
