feat(go): expose XAMLString and WithOutputFormat, honor __kcl_info_meta__ marker

PR-1 of issue #2047. Vendors pkg/format/xml + pkg/format/yaml from
kcl-lang/cli so kcl-go can render XML locally without a proto change,
then adds the attribute-aware XAML API.

- New XAMLString() on KCLResult mirrors YAMLString(); produced by a
  default xmlHook post-processor that runs when WithOutputFormat("xaml")
  is set.
- WithOutputFormat(format) Option sets the proto Format field. The CLI
  --format xml path is unaffected; this only matters for the XAML route.
- pkg/format/xml.Convert honours the new marker key (formerly
  __kcl_xml_attrs__) __kcl_info_meta__: splitAttrs reads the marker,
  emits the listed keys as name="value" attributes on the parent
  element, and deletes the marker so it is never rendered.
- pkg/format/yaml vendors ParseStream/IsStream (37 lines) so the xml
  hook can split multi-doc input.
- Renderer never emits a literal <__kcl_info_meta__> element even when
  the marker is missing.

PR-3 (kcl-lang/kcl) sets the marker; without that PR this code path
is inert. PR-2 (kcl-lang/cli) wires the same marker into --format xml.

Tests: pkg/format/xml (8), pkg/kcl (XAMLString mocked) all pass.
