Support for TrivialFileCatalog can be removed

[makortel]

Support for the Rucio catalog was added in 12_6_X with #37278 (that also made it the default catalog, that we have been using since with the exception of the hiccup at Tier0, see #40685 and #40755).

That was 2 years ago, so now one could start to wonder if and when we could remove the TrivialFileCatalog support from CMSSW master. That clean would potentially make other maintenance work such as #47050 easier.

@stlammel Any thoughts?

Hallo Matti,
i see no reason to keep the TFC support in CMSSW. (We need the TFC files at sites for the older CMSSW versions but if we backport the Rucio catalogue to the few CMSSWs where we update xrootd, we could even end support of those files at sites.)
Thanks,

Thanks @stlammel, we will then remove the TFC support from CMSSW master when we see fit.
