[lld][WebAssembly] Initialize bss segments using memory.fill
Previously we were relying on the dynamic loader to take care of this
but it simple and correct for us to do it here instead.
Now we initialize bss segments as part of `__wasm_init_memory` at the
same time we initialize passive segments.
In addition we extent the us of `__wasm_init_memory` outside of shared
memory situations. Specifically it is now used to initialize bss
segments when the memory is imported.
