The candidate list for empty input is all methods + all variables +
all constants + all keywords. It's a long list that is not useful.

* BaseScope to RootScope, move method objects constant under Methods
* Remove unused Splat struct
* Drop deeply nested array/hash type calculation from actual object. Now, calculation depth is 1

refactored for future extension
(https://github.com/ruby/irb/pull/707)
* Move completion implementation to completion/regexp_completor for future extension
* Remove constant CompletionProc and PerfectMatchedProc and add a class method
* Move document display logic to InputCompletor. Each completor only need to implement `completion_caididates` and `doc_namespace`
* Move display_document logic to RelineInputMethod
* Use RegexpCompletor directly. Not through class method of InputCompletor.
* RegexpCompletor extends BaseCompletor, move back definition to completion.rb
* Move display_document test to input_method test
* Stop re-initialize completor on each completion phase
* Store completor to ReadlineInputMethod's iver

Consider completion for this example: `foo.bar.b`
Without type information, it is hard to know the return value of the `bar`
method, so the current implementation interates through `ObjectSpace` to
get all possible candidates for the second method.
In small projects, the performance and accuracy are acceptable. But in
bigger projects, the performance is unacceptable and the accuracy is mostly
poor.
So this commit drops the support for chained methods' completion.
There are a few downsides of the current approach:
1. Because gem specs are lazily retrieved, this computation happens in
every irb completion test case, which is not necessary. (In tests we
don't cache the result of `retrieve_files_to_require_from_load_path`)
2. Gem::Specification.latest_specs is sensible to the content of
LOAD_PATH. And when combined with 1, tests fail "randomly" if they
try to mutate LOAD_PATH, even though the test subject it's something
else.
So by pre-computing and storing the gem paths in a constant, it guarantees
that the computation only happens once and it doesn't get affected by test
cases.
One argument could be made against the change is that, it'll store
unnecessary data for users that disable autocompletion. But the
counter-arguments are:
1. Since autocompletion is enabled by default, this should not be the
case for most users.
2. For users with autocompletion enabled, IRB already caches the
result of `retrieve_files_to_require_from_load_path` in memory, which
should have a similar size of GEM_SPECS. And we currently haven't
received any report about problems caused by such memory consumption.

In addition to String values, $LOAD_PATH can also take objects that
respond_to the `to_path` method, like Pathname objects. So `irb` should
be able to handle those objects too.
And if $LOAD_PATH contains objects that can't be converted into String,
`irb` should simply ignore it.

There are two directories where csv*/**/*.rb exist, lib/ and
test/, and depending on the order of tests, test/ may be placed
before lib/. In that case, as "shortest" names were not sorted,
csv/helper.rb will be the first candidate for "csv".

There are cases where ruby is installed without rdoc and e.g.
lib/irb/cmd/help.rb also handles the LoadError
Here is how to replicate the issue:
```
$ docker run -it alpine:3.13.3 sh
/ # apk add ruby ruby-irb ruby-io-console
/ # irb
irb(main):001:0> Class[TAB][TAB]
```
And you end up with something like:
```
irb(main):001:0> ClassTraceback (most recent call last):
