Switch SPIRV-Tools to use spirv.hpp11 internally (#4981)
Fixes #4960

* Switches to using enum classes with an underlying type to avoid
  undefined behaviour

spirv-fuzz: Tighten checks on null and undef pointers (#4367)
Adaps the transformations that add OpConstantUndef and OpConstantNull
to a module so that pointer undefs are not allowed, and null pointers
are only allowed if suitable capabilities are present.

Fixes #4357.

spirv-fuzz: Fix to TransformationInlineFunction (#3913)
This fixes a problem where TransformationInlineFunction could lead to
distinct instructions having identical unique ids. It adds a validity
check to detect this problem in general.

Fixes #3911.

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: Use unique_ptr<FactManager> in TransformationContext (#3844)
TransformationContext now holds a std::unique_ptr to a FactManager,
rather than a plain pointer. This makes it easier for clients of
TransformationContext to work with heap-allocated instances of
TransformationContext, which is needed in some upcoming work.

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.
