Imported and exported globals can now be mutable. In the Web binding, exported globals are now of type WebAssembly.Global, rather than converted to a JavaScript Number.

We've removed all ifdefs controlling this feature and it's riding the trains (with "type" renamed as "value" in the descriptor, the initial value as a separate parameter, and existing ref tests imported and passing). Looks like it'll be in FF62 unless something happens.
