PR to update AwsCredentialIdentity interface: https://github.com/smithy-lang/smithy-typescript/pull/1240

Testing

To-Do:

• [x] merge AwsCredentialIdentity interface PR above
• [x] run (updated) unit tests following above merge for all the credential providers that were modified.
• [x] run codegen for sts-defaultRoleAssumers since it copies these files to the client
• [x] copy .spec.ts for client-sts from codegen dir manually (test file isn't being copied properly)
