Make MakeFactoryMap generic and move to otelcol

[jade-guiton-dd]

Description

At the moment, receiver, scraper, processor, exporter, and extension each have their own version of the MakeFactoryMap function, which takes a list of Factories and returns it as a map, with the component name as the key (and an error if there is overlap). Because all versions are near-identical except for the Factory type used, and this function is only used in tests and in the code generated by OCB (components.go), it was suggested to make it generic and move it to the otelcol package.

This PR does exactly that. The old MakeFactoryMap functions are deprecated (and may be removed alongside their tests in a future release). I also had to make a few other odd changes to fit the new dependency graph.

Hm, CI says otelcorecol is out of date, but I get on my diff locally when running make genotelcorecol

Edit: The issue was that I was using a different version of Go from the CI, so the toolchain directive generated by ocb was different

Okay I think we have an infinite loop of make crosslink adds a replace, make genotelcorecol removes it, will think about this harder next week
