[WebAssembly] Rename GlobalSymbol types. NFC.

Purely a rename in preparation for adding new global symbol type.

We want to use GlobalSymbol to represent real wasm globals and
DataSymbol for pointers to things in linear memory (what ELF would
call STT_OBJECT).

This reduces the size the patch to add the explicit symbol table
which is coming soon!
