MDEV-16351 JSON_OBJECT() treats hybrid functions with boolean arguments as numbers

Browse Source 
Now the boolean data type is preserved in hybrid functions and MIN/MAX,
so COALESCE(bool_expr,bool_expr) and MAX(bool_expr) are correctly
detected by JSON_OBJECT() as being boolean rather than numeric expressions.
