spirv-fuzz: Pass submanagers to other submanagers when necessary (#3796)
This PR changes the fact manager so that, when calling some of the
functions in submanagers, passes references to other submanagers if
necessary (e.g. to make consistency checks).

In particular:

- DataSynonymAndIdEquationFacts is passed to the AddFactIdIsIrrelevant
  function of IrrelevantValueFacts

- IrrelevantValueFacts is passed to the AddFact functions of
  DataSynonymAndIdEquationFacts

The IRContext is also passed when necessary and the calls to the
corresponding functions in FactManager were updated to be valid and
always use an updated context.

Fixes #3550.
