[asm.js] [wasm] Move asm->wasm + WebAssembly switches to features.

Moving asm->wasm and webassembly to a feature will make them
ready to control from a Finch trial with kill-switch.

NOTE: This will mean --enable-wasm will be replaced with:
--enable-features=WebAssembly
and --enable-asm-wasm will be replaced with:
--enable-features=AsmJsToWebAssembly
