libavcodec/cbs_apv_syntax_template: limit tile to 2gb We do not support larger tiles as we use signed int Alternatively we can check this in apv_decode_tile_component() or init_get_bits*() or support bitstreams above 2gb length Fixes: init_get_bits() failure later Fixes: 421817631/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_APV_fuzzer-4957386534354944 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
