`builder.pair_label` is no good since it makes use of variables that the parser gem encountered.
Since the prism translator doesn't keep proper track of that information, the following code interprets
the implicit value as a local variable, even though it is not in scope:
```rb
def foo
bar = 123
end
{ bar: }
```

These changes were included when adding bundler plugin hooks for
`Bundler.require`, but they seem completely unrelated to that feature,
and have caused several issues.

Turns out, it was already almost correct. If you disregard \c and \M style escapes, only a single character is allowed to be escaped in a regex so most tests passed already.
There was also a mistake where the wrong value was constructed for the ast, this is now fixed.
One test fails because of this, but I'm fairly sure it is because of a parser bug. For `/\“/`, the backslash is supposed to be removed because it is a multibyte character. But tbh,
I don't entirely understand all the rules.
Fixes more than half of the remaining ast differences for rubocop tests
When parent scopes around an eval are forwarding parameters (like
*, **, &, or ...) we need to know that information when we are in
the parser. As such, we need to support passing that information
into the scopes option. In order to do this, unfortunately we need
a bunch of changes.
The scopes option was previously an array of array of strings.
These corresponded to the names of the locals in the parent scopes.
We still support this, but now additionally support passing in a
Prism::Scope instance at each index in the array. This Prism::Scope
class holds both the names of the locals as well as an array of
forwarding parameter names (symbols corresponding to the forwarding
parameters). There is convenience function on the Prism module that
creates a Prism::Scope object using Prism.scope.
In JavaScript, we now additionally support an object much the same
as the Ruby side. In Java, we now have a ParsingOptions.Scope class
that holds that information. In the dump APIs, these objects in all
3 languages will add an additional byte for the forwarding flags in
the middle of the scopes serialization.
All of this is in service of properly parsing the following code:
```ruby
def foo(*) = eval("bar(*)")
```

Tests worked around this but the incompatibility is not hard to fix.
This fixes 17 token incompatibilies in tests here that were previously passing

In https://github.com/ruby/prism/pull/3393 I made a mistake.
When there is no previous token, it wraps around to -1. Oops
Additionally, if a comment has no newline then the offset should be kept as is

Skipping detecting the encoding is almost always right, just for binary it should actually happen.
A symbol containing escapes that are invalid
in utf-8 would fail to parse since symbols must be valid in the script encoding.
Additionally, the parser gem would raise an exception somewhere during string handling

There appear to be a bunch of rules, changing behaviour for
inline comments, multiple comments after another, etc.
This seems to line up with reality pretty closely, token differences for RuboCop tests go from 1129 to 619 which seems pretty impressive
