Automatic update from web-platform-tests
Add 'writingsuggestions' tests for disabled elements and "unsupported"
input types

This CL adds tests for disabled elements and input types to which
writing suggestions are not applicable (eg <input type="color"/>).

The 'writingsuggestions' attribute setting/getting/reflection behavior
for these types of elements is identical to that of elements on which
writing suggestions should be generated. The User Agent is responsible
for ensuring that writing suggestions aren't applied to these types of
elements.
