Move CPUServiceBase, RootHandlers, and TimingServiceBase to FWCore/AbstractServices

[makortel]

PR description:

Following #47280 (where the package was created), motivated by #47175 (review). These three service base classes were "easy to move" from FWCore/Utilities. I envision two more PRs, one for RandomNumberGenerator and one for JobReport.

Resolves cms-sw/framework-team#1265

[Dr15Jones]

We do not normally put _interface_ here. Should this be consistent or do you want to change all the other files?

[makortel]

We have already some headers with _interface_ in FWCore. 4.1 in https://cms-sw.github.io/cms_coding_rules.html#4--technical-coding-rules-1 has the wording

If necessary to create a unique name, one can add the directory name

Strictly speaking the _interface is not necessary here, as there are no other headers with the same file name in this package.

I think the question of including _interface_ or not when not strictly necessary is somewhat of a personal taste, and I'd be fine with us not being fully consistent with that.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @antoniovilela, @sextonkennedy, @mandrenguyen, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
