JSON schema + JSON node vs. Perfetto category consistency (#869)

* Fix schema differences b/t JSON and perfetto

- "kernel_dispatches" (JSON) vs. "kernel_dispatch" (Perfetto) -> "kernel_dispatch"
- "scratch_api" (JSON) -> "scratch_memory"

* Update include/rocprofiler-sdk/cxx/serialization.hpp

- remove unnecessary includes causing circular dependency

* rocprofv3 docs

- Output formats
- JSON schema

* Spelling fix

* Update schema descriptions

* Improve assert log in test_perfetto_data
