hyukjinkwon 33e337c118 [SPARK-24709][SQL][FOLLOW-UP] Make schema_of_json's input json as literal only ... ## What changes were proposed in this pull request? The main purpose of `schema_of_json` is the usage of combination with `from_json` (to make up the leak of schema inference) which takes its schema only as literal; however, currently `schema_of_json` allows JSON input as non-literal expressions (e.g, column). This was mistakenly allowed - we don't have to take other usages rather then the main purpose into account for now. This PR makes a followup to only allow literals for `schema_of_json`'s JSON input. We can allow non literal expressions later when it's needed or there are some usecase for it. ## How was this patch tested? Unit tests were added. Closes #22775 from HyukjinKwon/SPARK-25447-followup.
