Remove Dream Overlay window name and update content descriptions.

This changelist sets the Dream Overlay window name to an empty string.
Omitting the name causes the window to be attributed to SystemUI by
Talkback for any visual element (status bar, complications) rather than
the dream.

This changelist also sets the content descriptions for a number of
icons in the dream overlay.

Test: manual
