Update several dependencies to their latest versions

[ivmarkov]

=== ESP-specific:

• Switches to esp-hal from main (rev e156b5453a8adc123b7a8b6aa08e0698ec87dfe8) which does have an updated 802.15.4 driver (Update the 802.15.4 driver to match the ESP-IDF C one w.r.t. behavior esp-hal#5006)
• Enables rx_on_when_idle = true
• Enables 20dBm instead of 8 by default

Overall, addresses most of #53

=== NRF-specific:

• Updates embassy-nrf to 0.9 (latest released)

=== edge-nal-specific:

• Updates to edge-nal 0.6 (latest), which in turn depends on the new embedded-io(-async) 0.7, as the echosystem is moving towards e-io 0.7 now

Pull request overview

Updates the ESP 802.15.4 radio integration and default radio configuration to improve OpenThread stability (notably around RX while idle and TX failure reporting), and adjusts the ESP example build to use an updated esp-hal/esp-radio source.

Changes:

• Change default radio config to rx_when_idle = true and TX power to 20 dBm.
• Update ESP radio driver integration to handle TX failure callbacks and attempt to surface received ACK frames.
• Patch ESP example dependencies to pull esp-hal/esp-radio from a git branch containing the updated 802.15.4 driver.
