HTML Media Capture: Update implementation, part 2.

HTML Media Capture: Update implementation, part 2.

The most recent version of the HTML Media Capture spec changes the `capture'
attribute from an enum to a boolean (the values that used to be passed to
the enum are now supposed to be extracted from the `accept' attribute).

Now that the Chromium side has landed, make the `capture' attribute in
HTMLInputElement a boolean and adjust the layout tests accordingly.
