RunCMakeTest: fix Truncation test definition

The `ctest_test` and `CTestCommandLine` truncation tests had multiple problems:
- escape expected result string to avoid regex matching
- specify the truncation size
- pass the truncation mode correctly into the test definition
- use unique test names

Issue: #23868
