Remove Crypto++ library

The tracked version of Crypto++ is going on 10 years old and doesn't
always compile properly on modern tooling.

This removes the entire subdirectory as well as references to files in
the build script.  Due to the number of files touched by this commit, I
opt to add its replacement in the next commit.
