freertos: Add test app sdkconfig

This commit adds the sdkconfig files for the FreeRTOS test app. These
configurations were dervied from the various legacy unit test app's
config files that included the FreeRTOS component.

This commit tries to keep a 1 to 1 config parity with the legacy test app.
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)
