## Motivation
When profiling multi-process applications where a parent process sends SIGKILL to child processes, the termination can occur before the profiler has a chance to flush collected data. This PR introduces a configurable delay before SIGKILL signals are forwarded, allowing profiling data to be captured before process termination. This is workaround.
## Technical Details
- Added new configuration setting `ROCPROFSYS_KILL_DELAY` (default: 0 seconds) to specify a delay before SIGKILL signals are forwarded to other processes
- Implemented `kill_gotcha` component that intercepts the `kill()` system call
- The gotcha only delays SIGKILL signals sent to external processes (pid > 0 and not self)
- Integrated `kill_gotcha_t` into the `preinit_bundle_t` for early initialization
- VA API tracing using Timemory gotcha wrappers.
- rocDecode API tracing integration using callback to ROCPROFILER_CALLBACK_TRACING_ROCDECODE_API
- Updated videodecode ctest to validate rocDecode APIs in perfetto trace.
[ROCm/rocprofiler-systems commit: 697d1ac02f]
- Renames the CMake option "ROCPROFSYS_USE_HIP" to "ROCPROFSYS_USE_ROCM"
- Remove the "ROCPROFSYS_USE_ROCM_SMI option. Controlled with the "ROCPROFSYS_USE_ROCM" option, instead.
- Runtime configuration can still toggle ROCPROFSYS_USE_ROCM_SMI to disable the sampling.
- Rename ROCPROFSYS_HIP_VERSION macro to ROCPROFSYS_ROCM_VERSION and remove blocks for `ROCPROFSYS_ROCM_VERSION < 60000`
- Remove ROCPROFSYS_USE_ROCTRACER and ROCPROFSYS_USE_ROCPROFILER
- Update test cases
- Update docker files and workflows to install cmake 3.21, which is required for the rocprofiler-sdk findPackage script.
- Removed rocm-6.2 from workflows due to a rocprofiler-sdk API change.
