Implement the `+whole-archive` modifier for `wasm-ld`

This implements the `Linker::{link_whole_staticlib,link_whole_rlib}`
methods for the `WasmLd` linker used on wasm targets. Previously these
methods were noops since I think historically `wasm-ld` did not have
support for `--whole-archive` but nowadays it does, so the flags are
passed through.
