Extracting functions in utils_func.cpp from ndt_scan_matcher as a library called localization_utils

[RyuYamamoto]

ndt_scan_matcher has util_func.cpp, which contains a useful functions used in this packages.

I have a suggestion, how about extracting these functions as a library called localization_utils?
(Path is autoware.universe/common/localization_utils)

Examples, would be perception_utils and motion_utils.
https://github.com/autowarefoundation/autoware.universe/tree/main/common/perception_utils
https://github.com/autowarefoundation/autoware.universe/tree/main/common/motion_utils

Currently, I am developing an evaluation tool for localization, and I have created and used functions similar to those in util_func.cpp, so it would be nice to use them from util_func.cpp.
(If there are util functions in ekf_localizer, I would to move to localization_utils.)

I also think that it would be better to move the functions in utils_func.cpp to the other package.
But maybe it doesn't necessarily have to be localization_utils package. Since the functions in the file seems very generic and applicable to other modules, I think adding those functions in tier4_autoware_utils may also be a choice.

thanks for the suggestion!
It certainly sounds like a good idea to move to tier4_autoware_utils.

I will think about proposal.
