Some background for this refactor:
1. Through a RubyLex instance's lifetime, the context passed to its methods
should be the same.
Given that `Context` is only initialised in `Irb#initialize`,
this should be true.
2. When `RubyLex` is initialised, the context object should be accessible.
This is also true in all 3 of `RubyLex.new`'s invocations.
With the above observations, we should be able to store the context in `RubyLex`
as an instance variable. And doing so will make `RubyLex`'s instance methods
easier to use and maintain.

In Ruby 3.2 or later, a nested constant access like `Foo::Bar::Baz` is
compiled to one instruction by the optimization https://github.com/ruby/ruby/pull/6187
We try to spot which sub-node caues a NameError in question based on the
constant name. We will give up if the same constant name is accessed in
a nested access (`Foo::Foo`).

When the main object is frozen, `IRB` wraps a `SimpleDelegator` around it.
But because `SimpleDelegator` doesn't delegate private methods, methods like
`require_relative` or `const_get` would cause error, which are needed for
lazily loading commands.
This commit works around this limitation by avoiding those private method calls
when setting up command execution.
methods
(https://github.com/ruby/irb/pull/502)
* Remove unnecessary parameter defaults
These methods are always called with tokens specified. So their default
`@tokens` value is never used and is misleading.
* Remove unnecessary context default
* Require tokens for `RubyLex#check_state`
sequence) to check_multiline_prompt
(https://github.com/ruby/reline/pull/458)
* pass unmodified lines to check_multiline_prompt
* Add test to check that output modified by output_modifier_proc is not passed to prompt_proc
(https://github.com/ruby/irb/pull/504)
* Simplify `RubyLex#set_prompt`
It's optional argument is never used by any caller.
* Remove the optional `p` argument from `RubyLex#set_input`
The argument is only used in a test case, which can be easily replaced by
a block argument.
Since RDoc does not parse string literals as documents, `eval` the
entire file instead of embedding in a here-document.
On the contrary, as `gem_original_require` alias is an implementation
detail but not for users, it should not be documented.

* Remove unnecessary Binding#source_location check
`Binding#source_location` was added in 2.6, which is the minimum supported
version now. So this check is no longer necessary.
* Remove unused IRB.delete_caller
This method was added in the earliest version of IRB:

But it's not currently referenced by anything. We can verify this with a
org-wide search result:

JRuby 9.4.0.0 introduced a change in case sensitivity in require statements,
meaning that an inclusion of `win32api` loaded Win32API.rb. With this change,
the require statement needs to be updated to the correct capitalization of the
filename to avoid reline failures in newer versions of JRuby.

Simplify part of regex ``[_a-zA-Z0-9]`` with equivalent shorthand ``\w``.
Replace case-when with match ``$1`` or default value ``?"``, making intention more clear.
