The change replaces bytecodealliance/wasmtime-go/v44 (CGo) with
tetratelabs/wazero (pure Go)
- CGo eliminated — wazero is pure Go, so the whole internal/wasm/sdk
runtime no longer needs a C toolchain/cross-compilation story.
- The "env glue module" trick (glue.go) is the right solution to
wazero's constraint that a HostModuleBuilder can't export memory.
- Process-wide CompilationCache (sync.OnceValue): each unique policy is
compiled once per process, and discarded/re-instantiated VMs are cheap.
- Simplification in vm.go — dropping the ~25 closure fields (evalOneOff,
eval, heapPtrGet, …) in favor of mod.ExportedFunction(name) + a generic
call/callVoid/callOrCancel
- All tests pass (incl. internal/wasm/sdk/internal/wasm,
internal/wasm/sdk/opa). evalCompat for ABI 1.1 is retained.

was invisible to the benchmark machinery -- it was on the other side of
the CGo divide 🙈
Fixes #7557.
