screen_ui: Word-wrap menu headers.
This CL adds ScreenRecoveryUI::DrawWrappedTextLines() to better handle
long menu header texts. It does a word wrap at spaces, if available.
This avoids fixed-length menu headers being truncated on small screens.
Bug: 64293520
Test: On bullhead, boot into recovery with --prompt_and_wipe_data, and
check the prompt texts.
