Part of #19774. This makes it twice as fast on my machine.
Stores a file at `node_modules/.deno/setup-cache.bin`, which contains
information about how the node_modules folder is currently setup.
Obviously there is a risk that this information will get out of date
with the current folder structure.
This is a reproduction and fix for a very obscure bug where the Deno
runtime locks up we end up polling an empty JoinSet and attempt to
resolve ops after-the-fact. There's a small footgun in the JoinSet API
where polling it while empty returns Ready(None), which means that it
never holds on to the waker. This means that if we aren't testing for
this particular return value and don't stash the waker ourselves for a
future async op to eventually queue, we can end up losing the waker
entirely and the op wakes up, notifies tokio, which notifies the
JoinSet, which then has nobody to notify 😢.

Relands #19463. This time the `ExtensionFileSourceCode` enum is
preserved, so this effectively just splits feature
`include_js_for_snapshotting` into `exclude_js_sources` and
`runtime_js_sources`, adds a `force_include_js_sources` option on
`extension!()`, and unifies `ext::Init_ops_and_esm()` and
`ext::init_ops()` into `ext::init()`.
This is a new op system that will eventually replace `#[op]`.
Features
- More maintainable, generally less-coupled code
- More modern Rust proc-macro libraries
- Enforces correct `fast` labelling for fast ops, allowing for visual
scanning of fast ops
- Explicit marking of `#[string]`, `#[serde]` and `#[smi]` parameters.
This first version of op2 supports integer and Option<integer>
parameters only, and allows us to start working on converting ops and
adding features.
… (#19463)"
This reverts commit ceb03cfb03.
This is being reverted because it causes 3.5Mb increase in the binary
size,
due to runtime JS code being included in the binary, even though it's
already snapshotted.

Remove `ExtensionFileSourceCode::LoadedFromFsDuringSnapshot` and feature
`include_js_for_snapshotting` since they leak paths that are only
applicable in this repo to embedders. Replace with feature
`exclude_js_sources`. Additionally the feature
`force_include_js_sources` allows negating it, if both features are set.
We need both of these because features are additive and there must be a
way of force including sources for snapshot creation while still having
the `exclude_js_sources` feature. `force_include_js_sources` is only set
for build deps, so sources are still excluded from the final binary.
You can also specify `force_include_js_sources` on any extension to
override the above features for that extension. Towards #19398.
But there was still the snapshot-from-snapshot situation where code
could be executed twice, I addressed that by making `mod_evaluate()` and
scripts like `core/01_core.js` behave idempotently. This allowed
unifying `ext::init_ops()` and `ext::init_ops_and_esm()` into
`ext::init()`.
This commit adds ability to print metrics of the Tokio
runtime to the console by passing "DENO_TOKIO_METRICS=1"
env var.
Metrics will be printed every second, but this can be changed
by "DENO_TOKIO_METRICS_INTERVAL=500" env var.
This switches syscall used in HTTP and WS server from "writev"
to "sendto".
"DENO_USE_WRITEV=1" can be used to enable using "writev" syscall.
Doing this for easier testing of various setups.
