Minor refactoring of the method get_expr_query at the classes sp_instr_cpush/sp_instr_cursor_copy_struct

Details

    Description

      Based on comments from the task MDEV-36079, lets do simple refactoring to exclude duplication of source code and fix the issue with handling the characters TAB, LF following immediately after the FOR/IS clause (currently, only the spaceship is treated as a separator after the FOR/IS clauses.
