1. Remove Object.hasOwn as LLRT doesn't implement it
2. Inline Node's implementations of the uint64 buffer functions as neither workers nor llrt supports it
3. Remove assert as neither workers nor llrt supports it (and its a single line :p)
4. Remove async_hooks as this is not standardised and cannot be polyfilled without runtime support. Fall back on the flag which says whether we are currently executing a run
