Added FinalPath implementation [12_2]

[Dr15Jones]

PR description:

OutputModules placed on a FinalPath do not cause unscheduled execution. This ability was requested by HLT.

As part of work, consolidated all copied code used in various OutputModuleBase implementations into one class.

Backport of #36398

PR validation:

Code compiles. All framework related unit tests (included the newly added ones) pass.

The failure is unrelated to this PR. SQLite is reporting a disk I/O failure.

The failure is unrelated to this PR. SQLite is reporting a disk I/O failure.

For the record, this error (occurring also in IBs) is reported in #36319.

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_12_2_X IBs (but tests are reportedly failing) and once validation in the development release cycle CMSSW_12_3_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
