Subject: feat(tui): add 'termsync' option (#25871)

The 'termsync' option enables a mode (provided the underlying terminal
supports it) where all screen updates during a redraw cycle are buffered
and drawn together when the redraw is complete. This eliminates tearing
or flickering in cases where Nvim redraws slower than the terminal
redraws the screen.
