Reviewed by Tim Horton.

Source/WebKit:

Adds support for displaying the "aria-label" attribute as the input view's label text in extra zoom mode. Also
adds support for grabbing the input label's text for testing.

Test: fast/forms/extrazoom/form-control-label-text.html

Tools:

Adds UIScriptController.formInputLabel, which asynchronously requests the input label text for the currently
focused element in extra zoom mode.

LayoutTests:

Adds a layout test to check that the label text of the focused form control in the input view can be sourced
from (1) the "placeholder" attribute, (2) the "title" attribute, (3) the "aria-label" attribute, or (4) an
associated label element.
