Integrate into ESP-IDF component registry

[gerekon]

This PR prepares TraceRecorder to be integrated into ESP registry. That allows IDF users to use it by specify component name in the project manifest files. For details see https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-guides/tools/idf-component-manager.html.

Having this merged you can upload component to ESP registry whenever new version is released.
In order to be able to upload component you need to register your namespace in ESP Registry. This PR implies that namespace is percepio and component name is tracerecorder. See https://docs.espressif.com/projects/idf-component-manager/en/latest/guides/packaging_components.html#publish-the-component.

Also you can publish new versions of the component automatically using GitHub actions. See https://docs.espressif.com/projects/idf-component-manager/en/latest/guides/packaging_components.html#upload-component-with-github-action

Still need to update example docs

I had to comment this because sourced file re-defines PERCEPIO_TRC_CFG_RECORDER_RTOS_FREERTOS defined above and IDF build system complains on it.

What can we do with this? Was it done intentionally?

Hi @eriktamlin, Could you please take a look at this and share your feedback? We’re happy to spend more time on it to get it merged.

Hi,
Sorry about the delay, we're working on a major update to the TraceRecorder so had to get some stuff down before integrating this.
This looks excellent!
I'm thinking we do an esp-idf branch so we can have the esp-idf specific files such as idf-component.yml and CMakeLists.txt without messing with any others.
Regarding the Kconfig in the root. I don't think that is used by anyone anymore so unless you explicitly need it (it looked like you mostly disabled it) I can just remove it instead.
