Add RNTupleTempSource and RNTupleTempOutputModule

[Dr15Jones]

PR description:

• Used PoolSource and PoolOutputModule as templates for their equivalent implementation using RNTuple. The new modules are meant to be used to further stress test the use of RNTuple in CMSSW. A different set of modules will be made for use during HL-LHC running.
• moved commits from RNTUPLE_X build to master.

PR validation:

Code compiles. Unit tests that pass in IBs pass after change.

resolves cms-sw/framework-team#1680

This pull request is fully signed and it will be integrated in one of the next master IBs (but tests are reportedly failing). This pull request will now be reviewed by the release team before it's merged. @sextonkennedy, @ftenchini, @mandrenguyen (and backports should be raised in the release meeting by the corresponding L2)
Notice This PR was tested with additional Pull Request(s), please also merge them if necessary: #49531

[makortel]

It is a bit weird though that the test with #49531 still showed a failure in TestRNTupleTempEventHistory. If the failure persists in IBs, I think it would be better to investigate there.
