add debug counters for local variable (lavr) access.
* debug_counter.h: add the following counters:
* lvar_get: counter for lvar get.
* lvar_get_dynamic: counter for lvar get from upper frames.
* lvar_set: coutner for lvar set.
* lvar_set_dynamic: coutner for lvar set from upper frames.
* lvar_set_slowpath: counter for lavr set using slowpath.
