Invalid KQL Expression Handling in Table Functions

Some invalid queries will fail earlier during parsing. Note: disabled the support for inline KQL expressions (the experimental Kusto language) when they are put into a kql table function without a string literal, e.g. kql(garbage | trash) instead of kql('garbage | trash') or kql($$garbage | trash$$). This feature was introduced unintentionally and should not exist. #61500 (Alexey Milovidov).
