SCI32: Remove unnecessary GfxFrameout::_frameNowVisible

This flag was used in SSCI to read from VRAM instead of from the
back buffer when a mouse interrupt was received in the middle of
a back buffer update. Since ScummVM controls when mouse events
are received via polling, it is not possible to receive a mouse
event in the middle of back buffer updates, so this code is
unnecessary for the engine to work properly.

This also fixes Valgrind warnings about use of uninitialized
memory at the start of the game, caused by not filling the cursor
memory buffers because `_frameNowVisible` was false until the first
frame was rendered.
