Input help text should be linked using ARIA

[Jono M]

It would be helpful for users of screen readers to be able to hear the help text assigned to form fields. Setting the aria-describedby attribute on the input is probably the best way to do this.
This is especially important for inputs which require a specific format (such as dates)

Affects latest master (using Orca 3.4.2)

Link form inputs to description text with aria-describedby (Bug #1259388)

All pieform elements (and inputs within composite elements) are now linked
using the aria-describedby attribute to their help text, to aid screen reader
users.
