Add basic profiler support
- Moved profiling-related helpers to profiling.mjs
- Added bottom-up profiler table
- Added mini-timeline overview wit opt/deopt events and usage graph
- Added flame-graph, pivoted on the currently selected function
Drive-by-fixes:
- Added/updated jsdoc type information
- Fixed static symbols (builtins, bytecodehandlers) that were both
added by the CppEntriesProvider and from code-events in the v8.log
- Support platform-specific (linux/macos) dynamic symbol loader by
adding a query path ('/v8/info/platform') to lws-middleware.js
- added css var --selection-color
