cmd/compile: add SSA config options useAvg and useHmul
This commit allows architectures to disable optimizations that need the
Avg* and Hmul* operations.
WebAssembly has no such operations, so using them as an optimization
but then having to emulate them with multiple instructions makes no
sense, especially since the WebAssembly compiler may do the same
optimizations internally.
Updates #18892
