424c7eaa40 LibJS: Fix replaceAll crash for overlapping search string positions 
The implementation of String.prototype.replaceAll cannot use AK's
implementation of String::find_all when finding the indices of the
search string in the source string. String::find_all will return indices
[0, 1] for String("aaa").find_all("aa") - i.e. it returns overlapping
results. This is not allowed by the JavaScript specification for
replaceAll.

e0c9f58b0c LibJS: Implement and use the GetSubstitution abstract operation 
Used by String.prototype.replace, String.prototype.replaceAll, and
RegExp.prototype [ @@replace ].

9f0aef6051 LibJS: Implement most of String.prototype.replaceAll 
This also renames ErrorType::StringMatchAllNonGlobalRegExp to
ErrorType::StringNonGlobalRegExp (removes "MatchAll") because this error
is now used in the same way from multiple operations.

596324ae9c LibJS: Rewrite String.raw() closer to the specification 
This includes not throwing a custom exception and using the
length_of_array_like abstract operation where required.

b6093ae2e3 LibJS: Implement String.prototype.substr according to the spec 
Fixes #6325

The JavaScript on the HTML Spec site that caused the crash is:
    window.location.hash.substr(1)

Of course, window.location.hash can be the empty string. The spec allows
for calling substr(1) on an empty string, but our partial implementation
wasn't handling it properly.

1db943e146 LibJS: Implement (mostly) String.prototype.match 
JavaScript has a couple of different ways to run a regular expression
on a string. This adds support for one more. :^)

2d8362cceb LibJS: Implement 'Relative Indexing Method' proposal (.at()) 
Still stage 3, but already implemented in major engines and unlikely to
change - there isn't much to change here anyway. :^)
