> %W allow escape sequences described in Escape Sequences. However the continuation line <newline> is not usable because it is interpreted as the escaped newline described above.

Instead, prefer `scan_byte` over `get_byte` since that already returns the byte as an integer, sidestepping conversion issues.
Fixes https://github.com/ruby/prism/issues/3582

This can get triggered even if the list of statements only contains
a single statement. This is necessary to properly support compiling
```ruby
defined? (;a)
defined? (a;)
```
as "expression". Previously these were parsed as statements lists
with single statements in them.

Mostly around newlines and line continuation.
* percent arrays need special backslash handling in the ast
* Fix offset issue for heredocs with many line continuations (used wrong variable as index access)
* More refined rules on when to simplify string tokens
* Handle line continuations in squiggly heredocs
* Correctly dedent squiggly heredocs with interpolation
* Consider `':foo:` and `%s[foo]` to not be interpolation

Also fixes a token incompatibility for the word separator. parser only considers whitespace until the first newline

When the line contains no real newline but contains unescaped ones, then there will be one less entry

This is a followup to #3373, where the implementation
was extracted

1. The string starts out as binary
2. `ち` is appended, forcing it back into utf-8
3. Some invalid byte sequences are tried to append
> incompatible character encodings: UTF-8 and BINARY (ASCII-8BIT)
This makes use of my wish to use `append_as_bytes`. Unfortunatly that method is rather new
so it needs a fallback

strings and word arrays
These are not line continuations. They either should be taken literally,
or allow the word array to contain the following whitespace (newlines in this case)
Before:
```
0...1: tSTRING_BEG => "'"
1...12: tSTRING_CONTENT => "foobar\\\n"
12...16: tSTRING_CONTENT => "baz\n"
16...17: tSTRING_END => "'"
17...18: tNL => nil
```
After:
```
0...1: tSTRING_BEG => "'"
1...6: tSTRING_CONTENT => "foo\\\n"
6...12: tSTRING_CONTENT => "bar\\\n"
12...16: tSTRING_CONTENT => "baz\n"
16...17: tSTRING_END => "'"
17...18: tNL => nil
```
