libpayload: video: Add support for font scaling with a factor

Browse Source 
This introduces support for font scaling with a factor provided via
Kconfig. In practice, the font itself is not scaled at any point in
memory and only the logic to determine whether a pixel should be filled
or not is changed.

Thus, it should not significantly impact either the access time or
memory use.
