[Tarantool-patches] [PATCH v12 3/8] module_cache: improve naming

[Cyrill Gorcunov via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

 - rename func_name to func_name_desc because
   it is not just a name but rather a name descriptor
   which includes symbol address

 - rename func_split_name to parse_func_name because
   the action of splitting name to parts is not what
   the function about, the function parses specification
   to fetch a descriptor

Part-of #4642
