Roctracer flush activity fix + perfetto.cfg (#317)

* Fix roctracer_flush_activity

- invoke roctracer_flush_activity() before disabling domains

* create comp::roctracer::flush()

- real issue was the global state when roctracer_flush_activity() was called

* formatting

* Update lib/omnitrace/library/components/roctracer.hpp

- provide definition of comp::roctracer::flush when OMNITRACE_USE_ROCTRACER is not defined

* omnitrace.cfg -> perfetto.cfg

- rename provided perfetto config file (omnitrace.cfg) to perfetto.cfg to avoid confusion

* Update lib/core

- gpu.hpp: defines for OMNITRACE_USE_{HIP,ROCTRACER,ROCPROFILER,ROCM_SMI}
- gpu.cpp
  - include core/hip_runtime.hpp
  - fix serialization of hipDeviceProp_t
- add hip_runtime.hpp
  -  ensure proper inclusion of hip_runtime.h
- add rccl.hpp
  - ensure proper inclusion of rccl.h

* Update lib/omnitrace/library

- rcclp.cpp
  - update includes for rccl
- roctracer.hpp
  - update includes for hip_runtime
- components/comm_data.hpp
  - update includes for rccl
- components/rcclp.hpp
  - update includes for rccl

* Update bin/omnitrace-avail/avail.cpp

- update includes for hip_runtime

* Update examples/rccl/CMakeLists.txt

- fix find_package for rccl when CI enabled

* Update CMakeLists.txt

- set cmake policy CMP0135 to NEW for cmake >= 3.24
  - Enable DOWNLOAD_EXTRACT_TIMESTAMP with ExternalProject_Add + URL download method

* Update timemory submodule

* Update pybind11 submodule

* Update pybind11 submodule

* Update lib/core/rccl.hpp

- include rccl.h only if OMNITRACE_USE_RCCL > 0

* Update lib/core/{gpu,hip_runtime}.hpp

* Update lib/core/gpu.cpp

- reintroduce some ppdefs

* Update lib/core/gpu.cpp

- fix ifdef on OMNITRACE_HIP_VERSION

* Update lib/core/gpu.cpp

- fix static assert for OMNITRACE_HIP_VERSION_MINOR when HIP version 4.x or older (unreliable minor versions)

* Update lib/core/gpu.cpp

- fix ifdef on OMNITRACE_HIP_VERSION

* Update lib/core/config.cpp

- disable OMNITRACE_PERFETTO_COMBINE_TRACES by default

* Update lib/core/perfetto.cpp

- if unable to open perfetto temp file, return the ReadTraceBlocking()

* Update lib/core/config.*

- flush tmpfile before closing
