We were seeing actions failures where the cache would be restored
"successfully" but then "Install CircuitPython deps" would fail:
# Step "Fetch IDF tool cache"

Adding ESP-IDF tools to PATH...
Not using an unsupported version of tool cmake found in PATH: 3.17.0.
I checked locally, and (even when dist/* is removed) it is very quick to
run each of the `idf_tools install` steps, about 2s total.
Try doing this to see whether it fixes the CI problems.
When handling negative steps, start and stop need to be mp_int_t so they
can be checked against a potential negative value during the for loop
used to set the slice values.
If interrupts are disabled, then calling sd_* functions will hardfault.
Instead, assume that it's safe to write if interrupts are disabled.

ARM recommends issuing a DSB instruction propr to issuing WFI, as it is
required on many parts suchas Cortex-M7. This is effectively a no-op on
the Cortex-M4 used in most NRF parts, however it ensures that we won't
be surprised when new parts come out.

In order to ensure we don't have any outstanding requests, disable
interrupts prior to issuing `WFI`.
As part of this process, check to see if there are any pending USB
requests, and only execute the `WFI` if there is no pending data.
This fixes#2855 on NRF.

Allow for passing `-DCFG_TUSB_DEBUG=1` or `-DCFG_TUSB_DEBUG=2` on the
command line to enable debugging tinyusb within circuitpython.

This update gives us access to a function we can run with interrupts
disabled to determine if the queue is empty.

On NRF, the `rtc_reset()` function is never called. As a result,
calls to `time.time()` return a cryptic error>
```
>>> import time
>>> time.time()
'' object has no attribute 'datetime'
>>>
```
This is because `MP_STATE_VM(rtc_time_source)` is not initialized
due to `rtc_reset()` never being called.
If `CIRCUITPY_RTC` is enabled, call `rtc_reset()` as part of the
`reset_port()` call. This ensures that `time.time()` works as expected.
