A file picker control (<input type=file>) is exposed as
a button in the accessibility tree. Previously the
filename chosen was only exposed in the accessible value,
like with other input elements - but most screen readers
were not reading the value, since it's not normal to
read the value of a button. So users couldn't tell what
file was chosen, or whether a file was chosen at all.

Fix this by making the accessible name include both the
filename (as already exposed in the value) and the
text of the "Choose File" button.

Add a test to confirm this is working correctly when a
file is selected.
