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

- Asynchronously load source map from sourceMappingURL
- Once loaded, annotate source positions with their original position
- Update script panel tooltip to include link to original source
- For the above, make DOM.element a slightly more flexible API,
allowing defining attributes and children
- Also fix ToolTipEvent handling to support nodes.
- Shuffle around some code to make createScriptNode async, in case
we want to load the source map when building the script node itself.
- Drive-by: make source markers a simple backgroundColor when there is
only one group.

This is mostly an auto-conversion done by several tools.
- use let / const
- use arrow functions
- use template strings
There are some additional manual rewrite required to modernize the
code further.
