ESP32-H2 support

[roma-jam]

Add esp32h2 support to the Direct Boot example.

To build an example:

• For esp32c3: cmake -B build -D target=esp32c3 -G Ninja .
• For esp32h2: cmake -B build -D target=esp32h3 -G Ninja .
• cmake --build build

Ah no, too early to move it from Draft. There are still problem with hello_world example.
For some reason, the cpu restarting because of the RTC WDT Reset.

Now everything works.
LED blinks, Hello, world! appears on the UART0 (TX pin) of the H2 board.

I have not squashed the commits (for easier review process). If I need to squash them before merge, please tell me and I will do that without any problem.
Thanks.

Great work @roma-jam, I left just a couple of nitpicky comments.

[roma-jam]

@igrr Thank you so much for the review! 🙏

I have fixed all the nitpicks.
If you have anything that in your opinion I can make better feel free to share.

@roma-jam I forgot one thing in the previous review, please also take a look and update the CI workflow:

• https://github.com/espressif/esp32c3-direct-boot-example/blob/main/.github/workflows/build.yml
• https://github.com/espressif/esp32c3-direct-boot-example/actions/runs/6253664164/job/17002678017?pr=13

@igrr No problem, I think that I can fix that.
But it seems that I am not able to trigger Actions, so I have changed the build.yml file and hope that it will work without any problem. Also, I have checked YML syntax with some online verification tool but I have not installed anything to verify it locally.

Probably, it is better do install any tool to be able to run build actions locally, isn't it?

@roma-jam Looks good to me to be merged, could you please clean up the history?
