This commit adds the ability to compile native modules for the RV64
platform, using "rv64imc" as its architecture name (eg.
"make ARCH=rv64imc" should build a RV64 natmod).
The rest of 64-bits relocations needed to build a native module are now
implemented, and all sample native modules build without errors or
warnings. The same Picolibc caveats on RV32 also apply on RV64, thus
the documentation was updated accordingly.
RV64 native modules are also built as part of the CI process, but not
yet executed as the QEMU port is not yet able to load and run them.

This commit adds support for RV32IMC native modules, as in embedding native
code into a self-contained MPY module and and make its exported functions
available to the MicroPython environment.
