vim-patch:9.2.0996: debugger: crash when evaluating a variable in a :def function frame (#41460)

Problem:  In the debugger ">up" and ">frame" select an older function call
          frame, but get_funccal_local_ht() and the related functions check
          current_funccal while returning a dictionary of the frame that
          get_funccal() selected.  A :def function keeps its local variables
          on the vim9 stack, its funccall_T has no l: and a: dictionaries and
          is allocated cleared, so with such a frame selected the returned
          hashtab has a NULL ht_array and evaluating any variable name at the
          debug prompt crashes in hash_lookup().
Solution: Check the funccal that is actually used and return NULL when it has
          no l: variables, so that the variable is reported as undefined
          instead.
