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)
No tests remaining in the target components.
Some further consolidations can be made here later, to combine target-specific
configs that don't need to be target-specific any more.
1. Add the 100 times test when the private key is generated by the random number;
2. Add the bt components to the unit-test-app/config directory.
3. Added the bt unit test case to CI.
