Add esp-hal-buzzer to drive a piezo-electric buzzer.

[AnthonyGrondin]

Moved over the esp-hal-buzzer package from esp-rs/esp-hal#1984

The provided example currently builds using a patch for esp-hal.

I'll put this in draft until esp-rs/esp-hal#1984 is merged so that we can update the patch to use the upstream repository

Thanks for moving this PR over! esp-rs/esp-hal#1984 has now been merged :)

[AnthonyGrondin]

I've updated the patch to use the upstream repo and added CI tests.

I also added alias in .cargo/config.toml so the example can be flashed with:
cd esp-hal-buzzer/ && cargo +esp esp32s3 --example buzzer

Thank you again for this PR, glad to finally be able to merge it! 😅 I've added you as a maintainer to the repository (for CODEOWNER purposes) and this all looks good to me.

Thank you. I'm glad to see the buzzer saga resolved 😄
