Try to cache only the `vcpkg/installed` directory instead of the whole
vcpkg directory, which appveyor says is too large to cache.

Hopefully this will speed up the appveyor builds at least a little bit.
We really need to switch to ninja at some point though.

See #465
To compile the build tool `bin2c`, add a target with `add_executable()`
on visual studio instead of using `HostCompile.cmake` because running
`cl.exe` fails in the appveyor visual studio environment, see:
https://developercommunity.visualstudio.com/content/problem/325122/c1356-unable-to-find-mspdbcoredll.html
Also update the dependencies module to latest.
appveyor build now tested to work.
