* Adding simple bare-bones test for end-to-end integration test for json validation against auto-generated JSON-schema grammars. * Adding additional examples as documented in #7789 . Also adding the ability to automatically output improperly failing grammars to debug output files so they can more easily be examined in the gbnf-validator program. * Uncommenting formerly commented tests so that they fail for others who are attempting to reproduce the bugs. * Merging improved schema test methods added by @ochafik in #7797 * Adding #define to temporarily remove failing tests so that this PR can pass CI, but still be useful for other PRs that want to leverage the framework. * Fixing nits from ochafik. Removing escape slashes, adding additional failing cases, fixing some other strings. * Fixing grammar indentation to be consistent throughout file.
