LD_PRELOAD librocprofiler-sdk-roctx.so when marker-trace enabled (#1057)

* LD_PRELOAD librocprofiler-sdk-roctx.so when marker-trace enabled

- this enables apps to link against old ROCTx (libroctx64.so) but get marker tracing in rocprofv3

* Update CHANGELOG

* Validation test for app linked to old (roctracer) ROCTx library

* Tweak scope of tool_counter_info

- causing "signal-unsafe call inside of a signal" error for ThreadSanitizer on mi200

* Fix handling of missing transpose-roctracer-roctx

* Disable rocprofv3 aborted-app test (ThreadSanitizer)

- ThreadSanitizer + mi200/mi300 + aborted-app results in a signal-unsafe call inside a signal that cannot be specifically suppressed as usual via rocprofv3_error_signal_handler for some unknown reason

* Add UndefinedBehaviorSanitizer job
