libpng: upgrade 1.6.43 -> 1.6.44

Changelog:
===========
- Hardened calculations in chroma handling to prevent overflows, and
  relaxed a constraint in cHRM validation to accomodate the standard
  ACES AP1 set of color primaries.
- Removed the ASM implementation of ARM Neon optimizations and updated
  the build accordingly. Only the remaining C implementation shall be
  used from now on, thus ensuring the support of the PAC/BTI security
  features on ARM64.
- Fixed the pickup of the PNG_HARDWARE_OPTIMIZATIONS option in the
  CMake build on FreeBSD/amd64. This is an important performance fix
  on this platform.
- Applied various fixes and improvements to the CMake build.
- Added fuzzing targets for the simplified read API.
- Fixed a build error involving pngtest.c under a custom config.
- Fixed and improved the config files for AppVeyor CI and Travis CI.
