lavc/vvc: Increase size of ctb_size_y
sps_log2_ctu_size_minus5 is between 0 and 2, with 3 reserved for future
use. The VVC decoder allows sps_log2_ctu_size_minus5 to be 3, and so
ctb_size_y should be at least 16 bits to prevent overflows. An
alternative patch would leave sps_log2_ctu_size_minus5 as 8 bits and
disallow sps_log2_ctu_size_minus5 = 3.
