Merge pull request chakra-core#2736 from Krovatkin:wasm-simd-collab

This PR includes
* A list of SIMD opcodes
* Initial extensions to WasmBytecodeGenerator and WasmBinaryReader to support reading and generating bytecodes for `extract`, `build` and arithmetic binary operations.
* Tests for these operations
* A few fixes

The fixes include:
* https://github.com/Microsoft/ChakraCore/pull/2736/files#diff-b0ef4db6dba17fc268e8745b695badceL1117
* https://github.com/Microsoft/ChakraCore/pull/2736/files#diff-9d396b386e20933b7bfbec028a04e8c9R248
* https://github.com/Microsoft/ChakraCore/pull/2736/files#diff-314ffb76644084b820e66bdfe3f879d9R377

In this version, we decided to not group SIMD operations into one case arm since this way we could encapsulate all SIMD-related reading logic in `ReadOpCode`. We could always move all SIMD ops into a separate case arm later.

I  temp disabled short-signature comparisons since I didn't know what the best way would be to extend it to support SIMD types.
