Until now, we've been treating the bottom of every line box fragment as
its baseline, and just aligning all the bottoms to the bottom of the
line box. That gave decent results in many cases, but was not correct.
This patch starts moving towards actual baseline calculations as
specified by CSS2.
Note that once layout is finished with a line box, we also store the
baseline of the line box in LineBox::m_baseline. This allows us to align
the real baseline of display:inline-block elements with other inline
content on the same line.
When the selection state of the node is SelectionState::End, the end
position of the selection within the fragment is not properly
calculated, because it forgets to subtract m_start from index_in_node,
unlike SelectionState::StartAndEnd. This resulted in a wrong selection
shadow being painted when the node is at the end of the selection.
This change resolves#5880.
This commit unifies methods and method/param names between the above
classes, as well as adds [[nodiscard]] and ALWAYS_INLINE where
appropriate. It also renamed the various move_by methods to
translate_by, as that more closely matches the transformation
terminology.

We'll want to remove the LibGUI dependency from the WebContent process.
This is the first basic step of removing unnecessary LibGUI includes
and swapping out GUI::Painter for Gfx::Painter.
