Fix cmake warnings

[jgiannuzzi]

This PR fixes some cmake warnings like:

CMake Warning at build/arm64-osx-debug/vcpkg_installed/arm64-osx/share/unofficial-utf8proc/unofficial-utf8proc-config.cmake:1 (message):
  find_package(unofficial-utf8proc) is deprecated.

  utf8proc provides CMake targets:



    find_package(utf8proc)
    target_link_libraries(main PRIVATE utf8proc::utf8proc)

Call Stack (most recent call first):
  build/vcpkg/scripts/buildsystems/vcpkg.cmake:908 (_find_package)
  cpp/CMakeLists.txt:11 (find_package)

ld: warning: ignoring duplicate libraries: '../vcpkg_installed/arm64-osx/debug/lib/libbrotlicommon.a', '../vcpkg_installed/arm64-osx/debug/lib/libbrotlidec.a', '../vcpkg_installed/arm64-osx/debug/lib/libbrotlienc.a', '../vcpkg_installed/arm64-osx/debug/lib/libsnappy.a'

It also removes Arrow/Parquet's transient dependencies from being referenced directly in cpp/CMakeLists.txt as the arrow port now properly adds them to our build.
