  [Object][Wasm] Use offset instead of index for Global address and store size (#81781)

Currently the address reported by binutils for a global is its index;
but its offset (in the file or section) is more useful for binary size
attribution.
This PR treats globals similarly to functions, and tracks their offset
and size. It also centralizes the logic differentiating linked from object
and dylib files (where section addresses are 0).
