refactor(ivy): remove unnecessary fac wrapper (#34076)

For injectables, we currently generate a factory function in the
injectable def (prov) that delegates to the factory function in
the factory def (fac). It looks something like this:

```
factory: function(t) { return Svc.fac(t); }
```

The extra wrapper function is unnecessary since the args for
the factory functions are the same. This commit changes the
compiler to generate this instead:

```
factory: Svc.fac
```

Because we are generating less code for each injectable, we
should see some modest code size savings. AIO's main bundle
is about 1 KB smaller.
