Adds a separate board for native64 instead of the `NATIVE_64BIT` workaround.
The files in `boards/native64` are more or less dummy files and just include
the `boards/native` logic (similar to `openlabs-kw41z-mini-256kib`).
The main logic for native is in `makefiles/arch/native.inc.mk`, `cpu/native`
and `boards/native`.
The remaining changes concern the build system, and change native board checks
to native CPU checks to cover both boards.
* 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`.
This fixes a signature mismatch between forward declaration and
implementation, which in turn fixes the following error during
compilation:
/home/maribu/Repos/software/RIOT/build/pkg/wolfssl/wolfcrypt/src/ge_low_mem.c:179:30: error: argument 1 of type 'unsigned char[64]' with mismatched bound [-Werror=array-parameter=]

Makefiles don't do comments, so these were forwarded into the variable.
*Most* users would expand the arguments to a shell where it'd be
ignored, but not all of them.

(This is also where the one version that is added here was removed).
With #10970 only existing *.c files will be added to SRC when using
the SUBMODULES mechanism, so SUBMODULES_NOFORCE (used to filter out
non existing source files) is now redundant so remove the usage.
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.
