Integrated perfetto + roctracer (#5)

- hosttrace library automatically collects and merges timestamps for HIP API calls and kernels with the host-side instrumentation
  - mostly eliminates the need for using external rocprof
- added thread_instruction_count in perfetto output
- increased hosttrace min_loop_address_range to 512
- disabled instrumenting functions with dynamic callsites by default
- miscellaneous cmake updates

* roctracer support

- fully integrated perfetto + roctracer outputs
- thread_instruction_count in perfetto
- increased min_loop_address_range to 512
- disabled instrumenting functions with dynamic callsites by default
- updated timemory submodule

* hosttrace_launch_compiler

- support for using an alternative compiler as needed via launch compiler
- elfio added as submodule (not currently used)
- miscellaneous cmake updates

* README update + host/device categories + misc

- timemory fix for TIMEMORY_ROCTRACER_ENABLED
- transpose fix

* papi_tuple_t -> papi_tot_ins

- minor fix to Findroctracer.cmake
