use the prebuilt library from libroot_julia_jll and ROOT_jll

- Use of Conda to install ROOT binaries replaced by _jll packages; ROOT_jll for
C++ ROOT binaries, and libroot_julia_jll for the wrapper library.
- Improved handling of wrapper build in case of use of ROOT binaries installed outside of Julia.
   - Compilation options handled by the new ROOTpreds package.
   - library not rebuilt during package precompilation in case it is up-to-date.
