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.
