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

spirv-fuzz: Avoid creating blocks without parents (#3908) 
The validity check during fuzzing and in unit tests is strengthened to
require that every block has its enclosing function as its parent.
TransformationMergeFunctionReturns is fixed so that it ensures parents
are set appropriately.

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: Fix bug in TransformationDuplicateRegionWithSelection (#3819) 
The following changes are introduced:

1. Entry block might have more than one predecessor, even if it is not
   a selection/loop merge block. However Apply method asserts that
   there is only one predecessor. Now, IsApplicable method ensures
   that there is only one predecessor.

2. In fuzzer pass we exclude both loop headers and selection headers
as potential exit blocks.

Fixes #3827.

spirv-fuzz: Return IR and transformation context after replay (#3846) 
Before this change, the replayer would return a SPIR-V binary. This
did not allow further transforming the resulting module: it would need
to be re-parsed, and the transformation context arising from the
replayed transformations was not available. This change makes it so
that after replay an IR context and transformation context are
returned instead; the IR context can subsequently be turned into a
binary if desired.

This change paves the way for an upcoming PR to integrate spirv-reduce
with the spirv-fuzz shrinker.

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.
