fix(naga): clippy bool_assert_comparison + benches zero-init enum

- rewrite assert_eq!(x, true/false) as assert!(x)/assert!(!x) in the serde round-trip
  tests (naga clippy --all-targets --all-features was not run locally before)
- benches glsl::Options.zero_initialize_workgroup_memory: true -> Polyfill (missed
  Phase-3 construction site; the other zero_init sites are hal::ProgrammableStage bools)
