1. Because `IRB.rc_file` always generates an rc file name, even if the
   file doesn't exist, we should check the file exists before trying to
   load it.
2. If any type of errors occur while loading the rc file, we should
   warn the user about it.

I propose introducing the capability to set the IRB completion kinds via an environment variable, specifically `IRB_COMPLETOR=type`.
This feature aims to enhance the Rails console experience by allowing Rails users to specify their preferred completion more conveniently.

Currently, when using the Rails console, there's no straightforward way to globally set the type completion across a Rails application repository.
It's possible to configure this setting by placing a `.irbrc` file at the project root. However, using a .irbrc file is not ideal as it allows for broad configurations and can potentially affect the production environment.
My suggestion focuses on allowing users to set the completion to 'type' in a minimal.

This enhancement would be particularly beneficial for teams writing RBS in their Rails applications.
This type completer, integrated with RBS, would enhance completion accuracy, improving the Rails console experience.

* Add command line option to select which completor to use

* Add test for completor argv

`IRB_USE_AUTOCOMPLETE=false`
(https://github.com/ruby/irb/pull/469)

* Allow using IRB_USE_AUTOCOMPLETE=false to disable autocompletion

Currently, the only 2 ways to disable autocompletion are:

1. Create `.irbrc` and set `IRB.conf[:USE_AUTOCOMPLETE] = false`
2. Add the `--noautocomplete` flag when using the `irb` executable

Both of them are less convenient than setting a env var and are
lesser known to devs.

And given the number of problems the autocompletion has (see #445), I
think we should allow disabling it with a simple `IRB_USE_AUTOCOMPLETE=false`.

* Mention some env var configs in the README

* Create a base TestIRB::TestCase class

* Save/restore encodings for tests that initializes InputMethod classes

Because `RelineInputMethod#initializes` calls `set_encoding`, which
changes stdio/out/err and Encoding's default encoding values, we need to
make sure any test that directly or indirectly (e.g. through Context)
initializes `RelineInputMethod` restores encodings.

`ReadlineInputMethod` also changes encodings but currently no tests
cover it.

* Remove unnecessary TestHelper module

Since we now have a base TestCase, without_rdoc can just live there.

https://no-color.org has been updated (jcs/no_color#83):

> Command-line software which adds ANSI color to its output by default
should check for a `NO_COLOR` environment variable that, when present
and **not an empty string** (regardless of its value), prevents the
addition of ANSI color.

Also add --script option to turn the option back on.

Previously there wasn't a way to get an interactive IRB session
and access arguments provided on the command line.

Additionally, handle `-` as script as stdin. In Unix-like tools, `-`
means to take standard input instead of a file.  This doesn't
result in exactly the same output for:

```
echo 'p ARGV' > args.rb; irb args.rb a b c
```

and

```
echo 'p ARGV' | irb - a b c
```

Due to how irb handles whether stdin is a tty.

However, this change allows use of `-` as a argument, instead of
giving an unrecognized switch error. This required some small
changes to context.rb (to handle `-` as standard input) and
input-method.rb (to have FileInputMethod accept IO arguments in
addition to strings).

Implements [Feature #15371]
