Fix generation of credentialType(bearer) for non-priority bearer operations

[alextwoods]

Fix generation of credentialType(bearer) for non-priority bearer operations - .credentialType(TOKEN) should only ever be set when an operation supports bearer as its first priority auth type - it should not be set when bearer is supported but not prefered (eg @auth[sigv4, bearer]).

Motivation and Context

This fixes an edge case when using legacy (non-sra) signing override on services with mixed sigv4 and bearer support. When a legacy (old, non-sra) signer override is set on the client/request, this code path is triggered and the presence of the Bearer CredentialType causes the AuthorizationStrategyFactory to return bearer instead of sigv4.

Modifications

• Updated the AuthUtils.isOpBearerAuth to isOpBearerAuthPreferred and ensure it returns true IFF (if and only if) the operation should use bearer auth as the first preferred auth scheme.

Testing

Add new test cases to cover.
