LibGfx+LibWeb: Allow inexact size lookups when requesting scaled fonts

Browse source 
For bitmap fonts, we will often not have an exact match for requested
sizes. Return the closest match instead of a nullptr.

LibWeb is currently the only user of this API. If it needs to be
configurable in the future to only allow exact matches, we can add a
parameter or another method at that time.
