```
wasm-linker: emit `target_features` section

When the result is not being stripped, we emit the `target_features`
section based on all the used features. This includes features
inferred from linked object files.
Considering we know all possible features upfront, we can use an
array and therefore do not have to dynamically allocate memory.
Using this trick we can also easily order all features based
the same ordering as found in `std.Target.wasm` which is the same
ordering used by LLVM and the like.

```
