refactor(core): Improve ergonomics of managing ASCII strings (#18498)
This is a follow-on to the earlier work in reducing string copies,
mainly focused on ensuring that ASCII strings are easy to provide to the
JS runtime.

While we are replacing a 16-byte reference in a number of places with a
24-byte structure (measured via `std::mem::size_of`), the reduction in
copies wins out over the additional size of the arguments passed into
functions.

Benchmarking shows approximately the same if not slightly less wallclock
time/instructions retired, but I believe this continues to open up
further refactoring opportunities.

perf(ext/websocket): use opAsync2 to avoid spread deopt (#18525)
This commit adds a new core API `opAsync2` to call an async op with
atmost 2 arguments. Spread argument iterators has a pretty big perf hit
when calling ops.

fix(core): remove async op inlining optimization (#17899)
Runtime generation of async op wrappers contributed to increased startup
time and core became unusable with
`--disallow-code-generation-from-strings` flag. The optimization only
affects very small microbenchmarks so this revert will not cause any
regressions.
