Pete Bacon Darwin 58cdc22791 fix(ngcc): handle UMD factories that do not use all params (#34660)
In some cases, where a module imports a dependency
but does not actually use it, UMD bundlers may remove
the dependency parameter from the UMD factory function
definition.

For example:

```
import * as x from 'x';
import * as z from 'z';
export const y = x;
```

may result in a UMD bundle including:

```
(function (global, factory) {
    typeof exports === 'object' && typeof module !== 'undefined' ?
        factory(exports, require('x'), require('z')) :
    typeof define === 'function' && define.amd ?
        define(['exports', 'x', 'z'], factory) :
    (global = global || self, factory(global.myBundle = {}, global.x));
}(this, (function (exports, x) { 'use strict';
...
})));
```

Note that while the `z` dependency is provide in the call,
the factory itself only accepts `exports` and `x` as parameters.

Previously ngcc appended new dependencies to the end of the factory
function, but this breaks in the above scenario. Now the new
dependencies are prefixed at the front of parameters/arguments
already in place.

Fixes #34653
