Tests: Expand JSON Schema value preparation coverage

Test nested `oneOf` schemas with multiple matching branches and combined `anyOf`/`oneOf` schemas through `wp_prepare_json_value_for_client()`, asserting the resulting JSON representation. Add three basic tests for `_wp_json_schema_matches_type()` while retaining the existing coverage for nesting and type inheritance.

Follow-up to [64592].
