stand alone test app. The following CI configurations are provided
- Default: Automatic light sleep with mostly default configurations
- Options: Enables all of the optional esp_pm features
- Limits: Limit tests esp_pm

configurations were dervied from the various legacy unit test app's
config files that included the FreeRTOS component.

Meaning, if FreeRTOS test were run on a particular target with a particular
config, that config will be represented in one of the test app's
sdkconfig.ci.XXX files.
However, the following configurations were removed for FreeRTOS tests:
- The "freertos_flash" option was removed due to redudancy (already tested in
freertos_options)
