Fix input alignment test reference
<!-- Please describe your changes on the following line: -->
In #10249 I added a ref test about text alignment in input element. But we couldn't delete the `float: left;` styled div because of a bug addressed here: #10280 . But it seems fixed now and we can finally remove the floated div in the reference file. Test is still passing.

Add the append method for the Headers API
<!-- Please describe your changes on the following line: -->
This commit adds the append method for the Headers API. @malisas and I are both contributors.
There are a few TODOs related:
- The script needs to parse the header value for certain header names to decide the header group it belongs
- There are possible spec bugs that could change what a valid header value looks like (related: [issue page](https://github.com/whatwg/fetch/issues/332))
There are WPT tests already written for the Headers API, but they will fail as the Headers API is not fully implemented.
