8fcdc57ae1 LibJS: Coerce named captures to an object before calling GetSubstitution 
Per the spec, before invoking the GetSubstitution abstraction, the named
capture groups (if not undefined) should be coerced to an object via the
ToObject abstraction.

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. :^)
