Upgrade arm-none-eabi compiler

It was 5 years out of date and didn't fully support C++20.

In doing so, flip off "freestanding" mode for the cortex-m4f compiler's
use of libstdc++.
This is because some libraries appear to have been using STL headers
that cannot be safely linked against in freestanding mode (e.g.,
<ostream>). I am unsure why the prior compiler was not catching this.
If this becomes a problem, we can disable it.
