tdf#157518: external: bundle zxcvbn-c

Integrates zxcvbn-c as a static library.

zxcvbn-c is C/C++ implementation of
https://dropbox.tech/security/zxcvbn-realistic-password-strength-estimation.

This is the first step for introducing a password strength
meter. Some example projects that utilize zxcvbn-c are
KeepassXC, monero-gui.

ExternalProject_zxcvbn-c takes care of the dictionary node
generation bits resulting in the dict-src.h

Then StaticLibrary_zxcvbn-c depends on
ExternalProject_zxcvbn-c and uses the generated bits and the
zxcvbn-c source to compile the library.

It should be possible to get rid of dictionary node
generation bit with a patch that includes a constant
dict-src.h that's what monero-gui does for example. But this
might also obfuscate what dict-src.h is.

Right now the dictionary that is included with zxcvbn-c only
targets English, so that might be something to improve upon.
