spirv-fuzz: Report fresh ids in transformations (#3856)
Adds a virtual method, GetFreshIds(), to Transformation. Every
transformation uses this to indicate which ids in its protobuf message
are fresh ids. This means that when replaying a sequence of
transformations the replayer can obtain a smallest id that is not in
use by the module already and that will not be used by any
transformation by necessity. Ids greater than or equal to this id
can be used as overflow ids.

Fixes #3851.

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.
