depends: add NO_HARDEN option

Add an option that when passed, will disable hardening options, and
pass `--disable-hardening` through to configure. Due to the way
we link libssp for Windows builds, they now fail (after #27118),
if building with depends, and configuring with --disable-hardening.
See:
https://github.com/bitcoin/bitcoin/pull/27118#issuecomment-1492606272.

This change would add a depends opiton such that, if someone wants to
build with, for windows, without hardening, they can do so. This may
also be useful when building for debugging.
