According to the spec, the values of both the chroma DC transform outputs and the corresponding quantization outputs should be within -(1 << 15) and ((1 << 15) - 1). This check has been now added to the functions, with an early exit when the constraints are not met. Bug = ossfuzz:65055 Test: mvc_dec_fuzzer
