halapi: Add new get_backend and put_backend with specific library name

Basically, hal_common_get_backend has used the promised libray name
for HAL backend like 'libhal-backend-[moodule name].so'. But, there are
some requirements that need to select the one HAL backend among the
multiple HAL backends on same device according to the role of use.

So that add the following two functions with new library_name argument.
- int hal_common_get_backend_with_library_name(enum hal_module module,
					void **data, const char *library_name);
- int hal_common_put_backend_with_library_name(enum hal_module module,
					void *data, const char *library_name);

[Constraints of library name]
This library_name argument must keep the naming rule as following:
-  'libhal-backend-[moodule name]-[extented name].so
