Referring to https://sourceforge.net/p/libjpeg-turbo/bugs/48, https://sourceforge.net/p/libjpeg-turbo/bugs/82, #15, #238, #253, and #619, valgrind and MSan have failed to properly detect data initialization by libjpeg-turbo's x86 SIMD extensions for the entire 14 years that libjpeg-turbo has been a project, resulting in false positives unless libjpeg-turbo is built with WITH_SIMD=0 or run with JSIMD_FORCENONE=1. This commit introduces a new C preprocessor macro (ZERO_BUFFERS) that, if set, causes libjpeg-turbo to zero certain buffers in order to work around the specific valgrind/MSan test failures caused by the aforementioned false positives. This allows us to more closely approximate the production configuration of libjpeg-turbo when testing with valgrind or MSan. Closes #781
