On the view-source page, generate anchor tags for any 'href' or 'src'
attribute value we come across. This handles both when the attribute
contains an absolute URL and a URL relative to the page.
This requires sending the document's base URL over IPC to resolve
relative URLs.

This has no visible effect, but internally it's also highlighting any
CSS and JS embedded in the page, which will be made use of later. We'll
also be able to use this code for highlighting CSS or JS files directly
in the future.
It's not a perfect fit - the syntax highlighters give specific styles to
their spans, which we then ignore and just use their data integer to
figure out which CSS class to give to the span. It feels cleaner to me
to produce HTML styled that way, instead of every token having
`style="color: ...; font-weight: ...; text-decoration: ...;"` set on
it.
Most of this new `to_html_string()` code is adapted from Serenity's
`TextEditor::paint_event()`, so it should be pretty solid.

amended to fix tiny conflict in CMakeLists.txt)
When we want to inject a CSS counter for a line, we need to be sure to
handle if we had previously opened a styled span for the current source
substring. For example, if we see a new line in the middle of a comment,
we will have previously opened the following tag:
<span class="comment">
So when injecting a new line and the <span class="line"> element (for
CSS counters), we need to close the previous span and insert a newly
opened tag to continue using the style.

Since "Character" tokens do not have an "end position", viewing source
drops the source contents following the final non-"Character" token.
By handling the EOF token and breaking out of the loop, we avoid this
issue.

This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
Which pretty much needs to be done together due to the amount of places
where they are compared together.
This also involves porting over StackOfOpenElements over to FlyString
from DeprecatedFly string to prevent a gazillion calls to
`.to_deprecated_fly_string` calls in HTMLParser.
This tokenizes a page's source to produce HTML with syntax highlighting.
The first implementation here is rather simple; we do not yet implement
code folding, line numbers, etc.
The goal is for this to be used as the View Source implementation for
all Ladybird chromes.
