kconfig: TraceRecorder Kconfig file for undefined symbols
kconfig: TraceRecorder Kconfig file for undefined symbols

Follow-up: #34843

This commit is a followup to PR #34843.
The Zephyr subsys/tracing/Kconfig file has a
`depends on ZEPHYR_TRACERECORDER_MODULE` but that symbol is only
available when the module is part of the manifest.

This commit adds the second part of the comment:
https://
github.com/zephyrproject-rtos/zephyr/pull/34843#discussion_r628154265

To ensure all Kconfig symbols are defined.

Without this commit, users without TraceRecorder will see following
checkpatch error:
```
ERROR   : Test KconfigBasic failed: Undefined Kconfig symbols:
