* Added arch_64bit feature and added it to all packages that require 32 bit.
* hacl, wolfssl: Fixed different types between function declaration and implementation.
* lwip: Add required flag for 64 bit and bug fix in `lwip_sock`.
* micro-ecc: Workaround for GCC warning when using `__int128`.
The https://github.com/mitls/hacl-c repo was deleted.
Getting the new upstream (https://github.com/project-everest/hacl-star)
to work nicely as a package requires some non-trivial work and in the
meantime all CI jobs will fail.
As a short-term solution, switch the upstream to a backup version of
the original repository.
Quoting the inner commit:
> Not all RIOT platforms provide a PRIx64 or even 64-bit printing.

> As the debug routines that actually use this definition are unlikely to

> platform support, may or may not produce correct output) is a suitable
> fix.
Prepare for handling pkg state with files. So it requires having the
path defined before declaring targets. In addition, it cleans up the
old git-download target.
