Members with the @httpQuery trait are mishandled in responses and response tests

[jbelkins]

Describe the bug

When a response includes a member with the @httpQuery trait, that trait is to be ignored and the value for that member is to be read from the response.

Instead, the member is set to nil and is excluded from equality checks during protocol response tests.

As a result, tests such as this one pass even though the logic being tested is incorrect in smithy-swift:
https://github.com/smithy-lang/smithy/blob/ae319f42ebd611d6564a9715089931905acbf315/smithy-aws-protocol-tests/model/restXml/http-query.smithy#L362

Expected Behavior

The test linked above should pass after checking all members of the response for equality.

Current Behavior

The linked test passes, but only because the member marked with the @httpQuery trait is not tested for equality.

Reproduction Steps

• Remove the .filter { ... } statement here, which excludes members marked with the @httpQuery trait from equality evaluation when comparing results of a response protocol test.
• Generate and run protocol tests.
• The test linked above will fail due to mismatch of the actual & expected output.

Possible Solution

No response
