LibGUI: Calculate unclamped_scrubber_size() as float

Browse source 
Large enough content ranges produced unclamped scrubbers sized zero,
effectively clamped by their integer type. This led to zero sized
page_increments and scrubbers which didn't budge on gutter events.
This fixes broken gutters in FontEditor and TextEditor for large
files.
