[whatwg] Make files attribute of the input element writable

[Nico Weber]

Hi,

The files attribute of the input element is currently marked readonly
[1], to protect from `myInput.files = "/etc/passwd"; myForm.submit()`.
Since its type is now FileList and not string, that's no longer
necessary.

Making the attribute writable would allow setting the files property
of an input element to dataTransfer.files from a drop handler. For
example, I would like to use this to create a larger drop-target for a
file input. Here's one request for this functionality:

Can the readonly restriction be removed from the spec?
