planner: collect and move correlated utility to util pkg

[AilinKid]

What problem does this PR solve?

Issue Number: ref #51664, ref #52714

Problem Summary:

What changed and how does it work?

// optimizetrace and costusage is isolated from util because core/base depended on them for
// interface definition. Ideally, the dependency chain should not be:
//
// `base` <- `util`/`util.coreusage` <- `core`
//    ^ +---------------^                  |
//    +------------------------------------+
//
// since `base` depended on optimizetrace and costusage for definition, we should separate
// them out of `util`/`util.coreusage` to avoid import cycle. It should be:
//
// util.optimizetrace/util.costusage  <- `base` <- `util`/`util.coreusage` <- `core`
//   				^   		            ^                   ||
//   				|   		            +-------------------+|
//                              +------------------------------------------------+
//

Hi @AilinKid. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
