  Build: Use wrappers rather than CMake object libs
  
  Some downstream projects need to adapt the libjpeg-turbo source code to
  non-CMake build systems, and the use of CMake object libraries made that
  difficult.  Referring to #754, the use of CMake object libraries also
  caused the libjpeg-turbo libraries to contain duplicate object names,
  which caused problems with certain development tools.  This commit
  modifies the build system so that it uses wrappers, rather than CMake
  object libraries, to compile source files for multiple data precisions.
  For convenience, the wrappers are included in the source tree, but they
  can be re-generated by building the "wrappers" target.
  
  In addition to facilitating downstream integration, using wrappers
  improves code readability, since multiple data precisions are now
  handled at the source code level instead of at the build system level.
  
  Since this will be pushed to a bug-fix release, the goal was to avoid
  changing any existing source code.  A future major release of
  libjpeg-turbo may restructure the libjpeg API source code so that only
  the functions that need to be compiled for multiple data precisions are
  wrapped.  (That is how the TurboJPEG API source code is structured.)
  
  Closes #817
