Don't enable default features for esp*-hal

Oookay, an unexpected side-effect of the test unification is that I'm not sure if we can do this. While esp-wifi ideally shouldn't enable default HAL features, we don't want to set every default feature for every example and CI test either. Unsure how to progress.

... we don't want to set every default feature for every example and CI test either ..

Unfortunately, I cannot think of another solution 🤔

How about a hidden feature that enables the esp32XX-hal default feature, which we can use for examples/ci? E.g

# This feature is not stable, for internal use only
_default = ["esp32-hal/default", "esp32s3-hal/default"]

Actually, it doesn't even need to be a feature. We can just enable default feature of the hal

-esp32c6 = "run --features esp32c6 --target riscv32imac-unknown-none-elf --features esp32c6-hal/embassy-time-timg0"
+esp32c6 = "run --features esp32c6 --target riscv32imac-unknown-none-elf --features esp32c6-hal/embassy-time-timg0 esp32c6-hal/default"

IMO this PR isn't blocked on esp-hal any more, whatever solution will be picked there will not affect esp-wifi. Thanks to mabez for the default feature hint, that was something new for me.
