Description

Extend the `TransformationAddSynonym` class by including the following cases:

- Make a synonym of `%true` as `OpAny` (a vector with `%true` somewhere in it)
- Make a synonym of `%true` as `OpAll` (a vector with `%true` everywhere in it)
- Make a synonym of `%false` in a similar manner
- Make a synonym of a boolean id `%b` via `OpAny` (a vector with `%b` somewhere and `%false` everywhere else)

Research direction

Start by reading the TransformationAddSynonym class and tracing how it currently creates boolean synonyms. Add coverage for OpAny and OpAll with %true, %false, and a boolean id %b, including the specified vector contents; done means all four listed cases are supported and the relevant spirv-fuzz tests pass.
