Issue 5324: \abs-fontsize and set-global-staff-size in books

The font buffering hashtable will provide an outdated LilyPond
scale factor after changing global staff size between books. Mainly
\abs-fontsize concerned, because \fontsize will usually not match
a Pango font-size used in a differently scaled book and fresh fonts
will have to be loaded anyway.

The straight-forward solution is to simply apply #ly:restet-all-fonts
from within #set-global-staff-size.

When creating several \books of different staff-sizes set by 
#(set-global-staff-size ...), markup in absolute font sizes (\abs-fontsize) 
will mess up spacing (font-metrics) in the subsecquent books.
