Support for Espressif Xtensa C/C++ compilers

Hi Folks!

We just implemented support for Espressif Xtensa compilers for analysis on both SonarQube, SonarCloud and SonarLint.

It is available right now on SonarCloud.
It will be available on SonarQube 10.2
It will appear in next versions of SonarLint and it will be announced then.
