Feat/ Espressif clang check and remove unwanted python traceback (IDF-11835)

[mfialaf]

1. Verify that Espressif clang is present, to prevent possible usage of system clang.
2. In case of error, raise SystemExit instead of RuntimeError to prevent unwanted Python traceback in output.

LGTM, maybe checking for clang-tidy instead of clang would be more relevant, since IIUC it's the clang-tidy which is call under the hood. It's just nitpick, no need to change it. Thank you

@mfialaf Thank you. LGTM in general. Could you please classify these commits as fixes instead of features?

@dobairoland @fhrbata @radimkarnis Thank you all for revirew!

I considered your comments and adjusted the code. PR should be ready.

@mfialaf Could you please correct the typo in the commit title in traceback?

Also, why is Espressif before clang-tidy? clang-tidy is not developed by Espressif.
