Add XML model test cases for enum and datetime properties

[Copilot]

Adds test coverage for XML payloads containing models with enum and datetime properties to packages/http-specs/specs/payload/xml.

Changes

ModelWithEnum

• New model type: ModelWithEnum with single status property of extensible union type
• Enum definition: Status union with "pending", "success", "error" variants
• Operations: GET/PUT endpoints at /payload/xml/modelWithEnum
• Mock API: Scenario handlers for both operations with "success" status value

Example payload:

<ModelWithEnum>
  <status>success</status>
</ModelWithEnum>

The extensible union allows any string value beyond the defined variants, following TypeSpec's standard enum pattern.

ModelWithDatetime

• New model type: ModelWithDatetime with datetime properties using different encodings
• Properties:
  • rfc3339 with @encode(DateTimeKnownEncoding.rfc3339) decorator
  • rfc7231 with @encode(DateTimeKnownEncoding.rfc7231) decorator
• Operations: GET/PUT endpoints at /payload/xml/modelWithDatetime
• Mock API: Scenario handlers for both operations testing both datetime encoding formats

Example payload:

<ModelWithDatetime>
  <rfc3339>2022-08-26T18:38:00.000Z</rfc3339>
  <rfc7231>Fri, 26 Aug 2022 14:38:00 GMT</rfc7231>
</ModelWithDatetime>

This section details on the original issue you should resolve

<issue_title>[specs] New test case for XML model with enum property</issue_title>
<issue_description>We need a new test case in https://github.com/microsoft/typespec/blob/main/packages/http-specs/specs/payload/xml/main.tsp to cover the scenario of an XML payload that is a model with a single property defined as an enum.
A possible example payload could look like:

<ModelWithEnum>
    <status>success</status>
</ModelWithEnum>

Where "status" is an extensible union with the following values: "pending", "success", "error".
The scenario should support both GET and PUT operations.

@copilot - This is great. Can you use the same process to add an additional test case to this PR, this time testing a model with datetime properties. It should test both "rfc3339" and "rfc7231" formatted datetime objects.

Added test case for XML model with datetime properties testing both rfc3339 and rfc7231 encodings in commit 22986dc.

The new ModelWithDatetime model includes:

• rfc3339 property with @encode(DateTimeKnownEncoding.rfc3339) - value: 2022-08-26T18:38:00.000Z
• rfc7231 property with @encode(DateTimeKnownEncoding.rfc7231) - value: Fri, 26 Aug 2022 14:38:00 GMT

Both GET and PUT operations are supported at endpoint /payload/xml/modelWithDatetime.

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Looks good to me. But you need approval from reviewers who has more access for specs folder.
