spirv-fuzz: Call by value and move in transformations (#4208)
Adapts all transformation classes so that their protobuf message is
passed by value and then moved into the message_ field.

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: Create synonym via OpPhi and existing synonyms (#3701)
A transformation that adds new OpPhi instructions to blocks with >=1
predecessors, so that its value depends on previously-defined ids of
the right type, which are all synonymous. This instruction is also
recorded as synonymous to the others.

The related fuzzer pass still needs to be implemented.

Fixes #3592 .
