Allocate frame buffer last_frame_uf conditionally

The buffer 'last_frame_uf' is used to store the non-loop
filtered reconstructed frame and is used only when
search_filter_level() is invoked. Hence, the memory
allocation is done accordingly.

For AVIF image encode with speed = 6,

             HEAP Memory reduction(%)
Resolution   threads=1    threads=4

HEAP memory reduction was measured using the following command.
$valgrind --tool=massif ./avifenc ...
