perf(core, runtime): Further improve startup time (#17860)

Browse source 
This commit further improves startup time by:

- no relying on "JsRuntime::execute_script" for runtime bootstrapping,
this is instead done using V8 APIs directly
- registering error classes during the snapshot time, instead of on
startup

Further improvements can be made, mainly around removing 
"core.initializeAsyncOps()" which takes around 2ms.

This commit should result in ~1ms startup time improvement.
