Wasm h to cpp (#926)

* Move WasmType function implementations to wasm.cpp

* Move Literal methods to wasm.cpp

* Reorder wasm.cpp shared constants back to top

* Move expression functions to wasm.cpp

* Finish moving things to wasm.cpp

* Split out Literal into its own .h/.cpp. Also factor out common wasm-type module

* Remove unneeded/transitive includes from wasm.h

* Add comment to try/check methods

* Rename tryX/checkX methods to getXOrNull

* Add missing include that should fix appveyor build breakage

* More appveyor
