wasm-linker: Allow specifying symbols to be exported
Notating a symbol to be exported in code will only tell the linker
where to find this symbol, so other object files can find it. However, this does not mean
said symbol will also be exported to the host environment. Currently, we 'fix' this by force
exporting every single symbol that is visible. This creates bigger binaries and means host environments
have access to symbols that they perhaps shouldn't have. Now, users can tell Zig which symbols
are to be exported, meaning all other symbols that are not specified will not be exported.
Another change is we now support `-rdynamic` in the wasm linker as well, meaning all symbols will
be put in the dynamic symbol table. This is the same behavior as with ELF. This means there's a 3rd strategy
users will have to build their wasm binary.
