libwebp: Fix CVE-2023-1999
There exists a use after free/double free in libwebp. An attacker can
use the ApplyFiltersAndEncode() function and loop through to free
best.bw and assign best = trial pointer. The second loop will then
return 0 because of an Out of memory error in VP8 encoder, the pointer
is still assigned to trial and the AddressSanitizer will attempt a double free.
