This initially uses the new diagnostic printer in `deno lint`,
`deno doc` and `deno publish`. In the limit we should also update
`deno check` to use this printer.
We were calling `expand_glob` on our excludes, which is very expensive
and unnecessary because we can pattern match while traversing instead.
1. Doesn't expand "exclude" globs. Instead pattern matches while walking
the directory.
2. Splits up the "include" into base paths and applicable file patterns.
This causes less pattern matching to occur because we're only pattern
matching on patterns that might match and not ones in completely
unrelated directories.
This commit adds `--unstable-hmr` flag, that enabled Hot Module Replacement.
This flag works like `--watch` and accepts the same arguments. If
HMR is not possible the process will be restarted instead.
Currently HMR is only supported in `deno run` subcommand.
Upon HMR a `CustomEvent("hmr")` will be dispatched that contains
information which file was changed in its `details` property.

This commit introduces "WatcherCommunicator" struct that
is used facilitate bi-directional communication between CLI
file watcher and the watched function.
Prerequisite for https://github.com/denoland/deno/pull/20876
The motivation is If I'm using deno lint --rules, I want to see all the
rules especially the one that have no tags, since the recommend ones are
already active
This change also prints the tags associated with the rule inline.
Renames the unstable `deno_modules` directory and corresponding settings
to `vendor` after feedback. Also causes the vendoring of the
`node_modules` directory which can be disabled via
`--node-modules-dir=false` or `"nodeModulesDir": false`.
This removes `ProcState` and replaces it with a new `CliFactory` which
initializes our "service structs" on demand. This isn't a performance
improvement at the moment for `deno run`, but might unlock performance
improvements in the future.
This gets SQLite off the flamegraph and reduces initialization time by
somewhere between 0.2ms and 0.5ms. In addition, I took the opportunity
to move all the cache management code to a single place and reduce
duplication. While the PR has a net gain of lines, much of that is just
being a bit more deliberate with how we're recovering from errors.
The existing caches had various policies for dealing with cache
corruption, so I've unified them and tried to isolate the decisions we
make for recovery in a single place (see `open_connection` in
`CacheDB`). The policy I chose was:
1. Retry twice to open on-disk caches
2. If that fails, try to delete the file and recreate it on-disk
3. If we fail to delete the file or re-create a new cache, use a
fallback strategy that can be chosen per-cache: InMemory (temporary
cache for the process run), BlackHole (ignore writes, return empty
reads), or Error (fail on every operation).
The caches all use the same general code now, and share the cache
failure recovery policy.
In addition, it cleans up a TODO in the `NodeAnalysisCache`.

Examples of bad title:
- fix #7123
- update docs
- fix bugs
2. Ensure there is a related issue and it is referenced in the PR text.
3. Ensure there are tests that cover the changes.
4. Ensure `cargo test` passes.
5. Ensure `./tools/format.js` passes without changing files.
6. Ensure `./tools/lint.js` passes.
7. Open as a draft PR if your work is still in progress. The CI won't
run
all steps, but you can add '[ci]' to a commit message to force it to.
8. If you would like to run the benchmarks on the CI, add the 'ci-bench'

This commit updates deno_lint crate to 0.41.0. The new version contains
a braking change that requries a minor code fix here, which is also
addressed in this commit.
We currently only do this for fmt. This makes it so they're excluded by
default, but you can still opt into these directories by explicitly
specifying them.
