* [double-conversion] Bump to 3.1.0
This release also allows removing the workarounds for calling
vcpkg_fixup_cmake_targets twice after renaming *LibraryDepends.cmake
because upstream didn't install *Targets.cmake files. That in turn fixes
using double-conversion on Linux.
* [harfbuzz] Fix cmake configs
When building cmake with autotools, a harfbuzz-config.cmake file gets
installed that makes find_package work. However when building with
cmake, that is omitted. Therefore include a patch from upstream pull
request
https://github.com/harfbuzz/harfbuzz/pull/1161
to fix that.
* [harfbuzz] Rename targets to unofficial-harfbuzz because they are not provided by upstream
