Revised runtime font management

The built-in fonts are loaded via FontPack, and the font table is now constructed dynamically based on available fonts.

A full set of variants (style, size) are prepared for each font, but some of the data gets allocated lazily when needed.

GmRun needed a larger allocation for fonts, so now all the fields are combined into a single bit field.

TODO: Glyph scaling, vertical offsets, and symbol lookup are still not fully working.
