Most boards enable the UART console because it's needed for USB (where USB
CDC creates a virtual UART), and for ctrl-C to work.
The `prj_minimal.conf` settings still use CONSOLE_SUBSYS.
Fixes issue #17608.

So that more tests can run successfully, and so users by default have more
heap for applications. Thin minimal configuration still has a 16k GC heap.

It needs to be at least this big for `tools/pyboard.py` to work, which is
used (among other things) by `tests/run-tests.py`.

And ctrl-C can now interrupt a time.sleep call. This uses Zephyr's k_poll
API to wait efficiently for an event signal, and an optional semaphore.

Zephyr renamed CONFIG_FLOAT to CONFIG_FPU to better reflect its semantics
of enabling the hardware floating point unit (FPU) rather than enabling
toolchain-level floating point support (i.e., software floating point for
FPU-less socs).
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
