This adds support for the lockfile and node_modules directory to the
lsp.
In the case of the node_modules directory, it is only enabled when
explicitly opted into via `"nodeModulesDir": true` in the configuration
file. This is to reduce the language server automatically modifying the
node_modules directory when the user doesn't want it to.
Closes #16510
Closes #16373
Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

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`.
This commit removes "Deno.core" namespace. It is strictly private API
that has no stability guarantees, we were supposed to remove it long time ago.

This commit changes default default behavior of type checking
for several subcommands.
Instead of type checking and reporting type errors only for local
files, the type checking is skipped entirely. Type checking can
still be enabled using the "--check" flag.
Following subcomands are affected:
- deno cache
- deno install
- deno eval
- deno run
This commit adds new "deno check" subcommand.
Currently it is an alias for "deno cache" with the difference that remote
modules don't emit TS diagnostics by default.
Prints warning for "deno run" subcommand if "--check" flag is not present
and there's no "--no-check" flag. Adds "DENO_FUTURE_CHECK" env
variable that allows to opt into new behavior now.
This commit changes flow in inspector code to no longer require
"Runtime.runIfWaitingForDebugger" message to complete a handshake.
Even though clients like Chrome DevTools always send this message on startup,
it is against the protocol to require this message to start an inspector
session.
Instead "Runtime.runIfWaitingForDebugger" is required only when running with
"--inspect-brk" flag, which matches behavior of Node.js.
This commit fixes prompts printed to the terminal when
running with "--inspect" or "--inspect-brk" flags.
When debugger disconnects error is no longer printed as
users don't care about the reason debugger did disconnect.
A message suggesting to go to "chrome://inspect" is printed
if debugger is active.
Additionally and information that process is waiting for
debugger to connect is printed if running with "--inspect-brk"
flag.
This commit fixes inspector integration with "deno test" subcommand
by waiting for inspector sessions to connect if "--inspect-brk" flag
is passed.
