scripts: analyze_suspend.py: Update to upstream v4.3

- config file support added
- dev mode for monitoring kernel source calls and async kernel threads
- custom command support for executing a user cmd instead of suspend
- proc mode support for monitoring user processes with cpu exec data
- kprobe support for custom function tracing
- advanced callgraph support for function debug
- many bug fixes and formatting upgrades
