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: Allow inapplicable transformations to be ignored (#4407)
spirv-fuzz features transformations that should be applicable by
construction. Assertions are used to detect when such transformations
turn out to be inapplicable. Failures of such assertions indicate bugs
in the fuzzer. However, when using the fuzzer at scale (e.g. in
ClusterFuzz) reports of these assertion failures create noise, and
cause the fuzzer to exit early. This change adds an option whereby
inapplicable transformations can be ignored. This reduces noise and
allows fuzzing to continue even when a transformation that should be
applicable but is not has been erroneously created.

destructor of FuzzerPass.

spirv-fuzz: Introduce TransformationContext (#3272)
Some transformations (e.g. TransformationAddFunction) rely on running
the validator to decide whether the transformation is applicable.  A
recent change allowed spirv-fuzz to take validator options, to cater
for the case where a module should be considered valid under
particular conditions.  However, validation during the checking of
transformations had no access to these validator options.

This change introduced TransformationContext, which currently consists
of a fact manager and a set of validator options, but could in the
future have other fields corresponding to other objects that it is
useful to have access to when applying transformations.  Now, instead
of checking and applying transformations in the context of a
FactManager, a TransformationContext is used.  This gives access to
the fact manager as before, and also access to the validator options
when they are needed.

spirv-fuzz: Eliminate spurious semicolons (#3025)
Some unintended semicolons that are harmless on most platforms led to
compiler warnings on another platform.

spirv-fuzz: Add fuzzer pass to change function controls (#2951)
A new pass that allows the fuzzer to change the 'function control'
operand of OpFunction instructions.

Fixes #2939.
