This change writes the module name to the name section of the wasm binary. We use the `-soname` argument to determine the name and we default the output file basename if this option is not specified. In the future we will likely want to embed the soname in the dylink section too, but this the first step in supporting `-soname`. Differential Revision: https://reviews.llvm.org/D158001
