Evaluate inference changes in reselect due to tuple type mapping changes

[DanielRosenwasser]

In #50831, we fixed a bug around ensuring that optional tuple elements always contain a missing/undefined type, even when a mapped type tries to remove them.

However, this had some impact on 2 calls to reduxjs/reselect. Occasionally undefined can spoil inference results, but it's not clear where that might be taking place in the library.

See here for a simplified version of the MergeParameters type that works with TS 4.7 and later.

FYI I was able to successfully use the MergeParameters type from Anders, although the publishing step to make the package work from 4.2...4.9 was awkward:

This investigation was resolved. reselect shipped the type provided by Anders. I think that this issue could be closed now :) cc @jakebailey
