Make sure to refresh the contents of text-<input> when pressing
backspace or delete key.
The methods 'handle_insert()' and 'handle_delete()' already had the call
to 'm_browsing_context.active_document()->force_layout()' so let us also
add it to 'handle_delete_character_after()'.

We renamed the Frame class to BrowsingContext a while back, but forgot
to update some variable names.

Browsing contexts are defined by the HTML specification, so let's move
them into the HTML directory. :^)

This better matches the spec nomenclature. Note that we don't yet
*retrieve* the active document according to spec.

The "Box" suffix added nothing here.

This makes it much clearer what this cast actually does: it will
VERIFY that the thing we're casting is a T (using is<T>()).

The previous behavior was to always VERIFY that the UTF-8 bytes were
valid when iterating over the code points of an UTF8View. This change
makes it so we instead output the 0xFFFD 'REPLACEMENT CHARACTER'
code point when encountering invalid bytes, and keep iterating the
view after skipping one byte.
Leaving the decision to the consumer would break symmetry with the
UTF32View API, which would in turn require heavy refactoring and/or
code duplication in generic code such as the one found in
Gfx::Painter and the Shell.
To make it easier for the consumers to detect the original bytes, we
provide a new method on the iterator that returns a Span over the
data that has been decoded. This method is immediately used in the
TextNode::compute_text_for_rendering method, which previously did
this in a ad-hoc waay.
This also add tests for the new behavior in TestUtf8.cpp, as well
as reinforcements to the existing tests to check if the underlying
bytes match up with their expected values.

Our "frame" concept very closely matches what the web specs call a
"browsing context", so let's rename it to that. :^)
The "main frame" becomes the "top-level browsing context",
and "sub-frames" are now "nested browsing contexts".

This patch updates the Page::keydown_event event handler to implement
crude Unicode support. It implements new method in EditEventHandler to
more easily handle deleting a single character after the cursor.
Furthermore, it makes use of the previously implemented methods to
increment and decrement the cursor position, which take into account
that Unicode codepoint may be multiple bytes wide.
This means it is now possible to mostly edit Unicode in editable DOM
nodes without any crashes. :^)

The mutation algorithms now more closely follow the spec and
fixes some assertion failures in tests such as Acid3 and Dromaeo.
The main thing that is missing right now is passing exceptions to the
bindings layer. This is because of issue #6075. I spent a while trying
to work it out and got so frustrated I just left it as a FIXME. Besides
that, the algorithms bail at the appropriate points.
This also makes the adopting steps in the document more spec compliant
as it's needed by the insertion algorithm. While I was at it, I added
the adoptNode IDL binding.
This adds a bunch of ancestor/descendant checks to TreeNode as well.
I moved the "remove_all_children" function to Node as it needs to use
the full remove algorithm instead of simply removing it from
the child list.
