Add support for device counter colleciton ioctl Adds support for the device counter collection IOCTL. This IOCTL allows for device wide counters to be collected even if the queue is not intercepted by rocprofiler-sdk (required for system profilers). A test is also included which checks this behavior by creating a queue that does not have profiling enabled on it and checks to see if SQ counters can be read from it. Note: this test will be skipped if the KFD version does not contain this IOCTL. Right now the check is "soft" in that if the IOCTL is present and there is an error with permissions, rocprofiler will continue but will print an error stating that system wide device profiling and collected counter values may be degraded. This is primarily to avoid breaking existing users (like PAPI) who may not need the IOCTL's capability and to give them time to update. Co-authored-by: Benjamin Welton <ben@amd.com>
