Clemens Backes b83c5a06c5 [wasm] Refactor WasmFeatures
Make WasmFeatures a proper class which uses an EnumSet under the hood.
This way, it inherits all behaviour of EnumSet like comparison, merge,
etc.
Accesses change from being simple field access into the struct to
actually bit tests in the EnumSet.
