Prototype new SIMD multiplications (#3291)

Including saturating, rounding Q15 multiplication as proposed in
https://github.com/WebAssembly/simd/pull/365 and extending multiplications as
proposed in https://github.com/WebAssembly/simd/pull/376. Since these are just
prototypes, skips adding them to the C or JS APIs and the fuzzer, as well as
implementing them in the interpreter.
