This commit changes "eager ops" to directly return a response value
instead of calling "opresponse" callback in JavaScript. This saves
one boundary crossing and has a fantastic impact on the "async_ops.js"
benchmark:

Prerequisite for https://github.com/denoland/deno/pull/18652
The CLI docs suggested that all deno subcommands no longer type-check by
default. This is only the case for some subcommands, and this PR
clarifies the CLI docs in this regard.
- bump deps: the newest `lazy-regex` need newer `oncecell` and
`regex`
- reduce `unwrap`
- remove dep `lazy_static`
- make more regex cached

`current_dir().unwrap()` joined with a Path is equivalent to the
implementation in `resolve_from_cwd()`. Manually tested on Ubuntu 22.04
and Windows 11.

This commit abstracts out the specifics of the underlying system calls
FS operations behind a new `FileSystem` and `File` trait in the
`ext/fs` extension.
This allows other embedders to re-use ext/fs, but substituting in a
different FS backend.
This is likely not the final form of these traits. Eventually they will
be entirely `deno_core::Resource` agnostic, and will live in a seperate
crate.

Fixes #6259.
Adds the location for v8 syntax errors to the message (`message += " at
{location}"`) when rethrowing them for dynamic imports.
Discussing with @bartlomieju on discord I proposed just preserving v8's
error and not reconstructing it, allowing the standard stack trace to
just point to the syntax error instead of the dynamic import. But on
further thought this way has parity with SWC's syntax errors + has the
advantage of showing both the syntax error and dynamic import location.
```ts
// temp.js
await import("./temp2.js");
// temp2.js
function foo() {
await Promise.resolve();
}
// Before:
// error: Uncaught (in promise) SyntaxError: Unexpected reserved word
// await import("./temp2.js");
// ^
// at async file:///.../temp.js:1:1
// After:
// error: Uncaught (in promise) SyntaxError: Unexpected reserved word at file:///.../temp2.js:2:3
// await import("./temp2.js");
// ^
// at async file:///.../temp.js:1:1
```
This reloads an npm package's dependency's information when a
version/version req/tag is not found.
This PR applies only to dependencies of npm packages. It does NOT yet
cause npm specifiers to have their dependency information cache busted.
That requires a different solution, but this should help cache bust in
more scenarios.
Part of #16901, but doesn't close it yet
Turns out `autoprefixer` is a better reproduction case then
`microbundle`.
Fixes #18535
Fixes #18600

This introduces a new built-in `unset` command to `deno task` by bumping
deno_task_shell to the latest version 0.11.0. Also this includes a fix
on how `deno task` handles empty environment variables (see
https://github.com/denoland/deno_task_shell/pull/80 for details).
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.
This commit updates the `Deno.Kv` API to return the new commited
versionstamp for the mutated data from `db.set` and `ao.commit`. This is
returned in the form of a `Deno.KvCommitResult` object that has a
`versionstamp` property.
