FormFileUpload does not allow upload the same file after error

[alefesouza]

Description

The FormFileUpload currently doesn't emit the onChange event when you choose the same file again.

A solution to it would be implement a new event prop that emits when click on the <input type="file"> element, then the parent component can clear the file input when clicking again to choose a new file.

See Automattic/woocommerce-payments#460.

Step-by-step reproduction instructions

1. Go to a page that has the FormFileUpload component with a onChange event.
2. Choose any file.
3. Choose the same file again.

It will not emit the onChange event again, not working as expect for the end user.
