newbitmaps: Refine font and text generation.

The bmpblk build scripts used to rely on lots of pre-generated resources, and
the HWID font data was fixed to x86 special size & scaling parameters.

Since the screens now rely on more platform dependent parameters, this CL
refined whole flow so fonts are now generated and processed (ex, re-scale) in
the same way as other text messages.

BUG=chrome-os-partner:11078
TEST=make # x86 and arm bitmaps both works.
