esp32/modesp32.c: Add mcu_temperature() function for C3/S2/S3 devices.

[ricksorensen]

For ESP32C3/S2/S3 IDFv5 exposes new internal temperature API which is different than base ESP32, IDFv4.

Thanks to @robert-hh for cleaner code and testing sensor capability in these devices.

See discussion #10443

Looks good to me. Tested it on custom S3 and C3 boards and seems to work well in my brief test.

[ricksorensen]

Thanks for checking

[projectgus]

This looks very useful, thanks @ricksorensen !

[projectgus]

This is a nitpick but please use the same chip naming schema as Espressif (and elsewhere in the docs), i.e. ESP32-C3, ESP32-S2, etc.

[ricksorensen]

Will update soon. Just need to get my courage up for trying to update pull request correctly...

[projectgus]

I don't know if this is useful, but jim has some tips here: https://github.com/jimmo/git-and-micropython?tab=readme-ov-file#i-want-to-make-changes-to-the-commits-my-pr--branch

If all else fails, making a new commit and pushing it to this branch is fine - we can squash the commits down before merging.

This is an automated heads-up that we've just merged a Pull Request
that removes the STATIC macro from MicroPython's C API.

See #13763

A search suggests this PR might apply the STATIC macro to some C code. If it
does, then next time you rebase the PR (or merge from master) then you should
please replace all the STATIC keywords with static.

Although this is an automated message, feel free to @-reply to me directly if
you have any questions about this.

@Rumidom I believe all the newer architectures (C2, S2, S3 .. C6?) use the newer IDF 5.x libraries. This PR is an attempt to include them but has not been integrated yet. Part of that is because I have not completely figured out how to fix all the errors, and part is fitting in with the micropython development process.
This PR should give a new temperature function (returning deg celsius) instead of the older ESP32 raw_temperature.
The current code has raw_temperature() functioned only if CONFIG_IDF_TARGET_ESP32 is defined - which is not for the S2/S3/C3/C6 variants.

The error may be caused by your habit or merging the master branch into your PR branch, instead for rebasing you branch onto the master. I do not know how to fix that. Maybe it's easier to create a new branch from the actual master and then cherry-pick the commit that make up you PR from the previous branch. Like, when you checked out the new branch:

git checkout master
git checkout -b esp32_temp_new
git cherry-pick

And then re-edit esp32/modesp.c to change STATIC into static. The above mentioned has is 798fb80, but I do not know if it's the same on your PC.
