[WebAssembly] Fix imported function symbol names that differ from their import names in the .o format
Add a flag to allow symbols to have a wasm import name which differs from the
linker symbol name, allowing the linker to link code using the import_module
attribute.
This is the MC/Object portion of the patch.
