This commit does major refactor of "Worker" and "WebWorker",
in order to decouple them from "ProgramState" and "Flags".
The main points of interest are "create_main_worker()" and
"create_web_worker_callback()" functions which are responsible
for creating "Worker" and "WebWorker" in CLI context.
As a result it is now possible to factor out common "runtime"
functionality into a separate crate.
This commit disables source mapping of errors
for standalone binaries. Since applying source
maps relies on using file fetcher infrastructure
it's not feasible to use it for standalone binaries
that are not supposed to use that infrastructure.
This commit makes the file watcher continue to work even if module
resolution fails at the initial attempt, allowing us to execute `run`
or `bundle` subcommand when a script has invalid syntax. In such
cases, the watcher observes a single file that is specified as an
command line argument.
Fixes panic occurring in worker when "self.close()" is called
at the top level, ie. worker shuts down while
module evaluation promise hasn't yet resolved.
This commit adds support for "--watch" flag for "bundle"
and "fmt" subcommands.
In addition to this, it refactors "run --watch" command so that
module resolution will occur every time the file watcher detects
file addition/deletion, which allows the watcher to observe a file
that is newly added to the dependency as well.
This commit rewrites scripts in "tools/" directory
to use Deno instead of Python. In return it allows
to remove huge number of Python packages in "third_party/".
This commit rewrites file watcher used with --watch flag.
Instead of creating new watcher after each restart, only a single
watcher is created for whole process. Additionally debouncing
mechanism has been added to prevent infinite restart loops
if multiple files were changed in quick succession.

Previously, entering a single ']' would cause repl to forever accepting
new lines, due to that `ValidationResult::Invalid` would actually be
consumed by the editor itself while continue building the lines. Instead
we should mark it as `Valid` and send the bad input for evaluation to
get the proper error from V8.
Before:
```
> ]
(you can keep entering new line here, and it will never consume input
until you Ctrl-C)
```
After:
```
> ]
Uncaught SyntaxError: Unexpected token ']'
>
```
This writes all evaluaton results to stdout regardless if the result is
an error or not.
This matches the behavior of other read-eval-print-loops like Node.
This commit fixes test runner by awaitning "Deno.runTests()" call,
which ensures proper error is returned when there's an unresolved
promise that's being awaited.
This commit changes implementation of top-level-await in "deno_core".
Previously promise returned from module evaluation was not awaited,
leading to out-of-order execution of modules that have TLA. It's been
fixed by changing "JsRuntime::mod_evaluate" to be an async function
that resolves when the promise returned from module evaluation also
resolves. When waiting for promise resolution event loop is polled
repeatedly, until there are no more dynamic imports or pending
ops.
* Revert "refactor: Worker is not a Future (#7895)"
This reverts commit f4357f0ff9.
* Revert "refactor(core): JsRuntime is not a Future (#7855)"
This reverts commit d8879feb8c.
* Revert "fix(core): module execution with top level await (#7672)"
This reverts commit c7c7677825.
This commit fixes implementation of top level await in "deno_core".
Previously promise returned from module execution was ignored causing to execute
modules out-of-order.
With this commit promise returned from module execution is stored on "JsRuntime"
and event loop is polled until the promise resolves.
This makes use of a default referrer when its empty in repl mode so that
dynamic imports work in the global evaluation context.

This ports the REPL over to Rust and makes use of an inspector session to run a REPL on top of any isolate which lets make full use of rustylines various things like validators and completors without having to introduce a bunch of hard to test internal ops and glue code.
An accidental but good side effect of this is that the multiple line input we previously had is now an editable multi-line input prompt that is correctly stored in the history as a single entry.
This commit adds basic support for collecting coverage
data using "deno test".
Currently the report is only a text added to the end
of output from "deno test".
