```
wasm-linker: create TLS Wasm globals correctly

Previously, they were only created when we had any TLS segment.
This meant that while the symbol existed, the global itself wouldn't.
The result of this was a crash during symbol names writing as it
would attempt to write the symbol name of a global that didn't exist.
Now we always create them, and instead update its `init` value during
`setupMemory`.

In the future, the entire symbol (and global) will be removed by
the garbage collector.
