[WebAssmebly] Add support for defined wasm globals in MC and lld This change add support for defined wasm globals in the .s format, the MC layer, and wasm-ld Currently there is no support custom initialization and all wasm globals are initialized to zero.

[WebAssembly] Add assembly syntax for mutable globals This adds and optional ", immutable" to the end of a `.globaltype` declaration. I would have prefered to match the `.wat` syntax where immutable is the default and `mut` is the signifier for mutable globals. Sadly changing the default would break backwards compat with existing assembly in the wild so I think its best to stick with this approach. Differential Revision: https://reviews.llvm.org/D87515
