Removing Typography as a runtime dependency

[charlesroddie]

What information do we need from LayoutFarm/Typography?

I think we should get this information and store it, probably in a file. Then the information doesn't need to be extracted at runtime.

Benefits to apps:

• deployment size
• reduced memory usage (Control Typography memory usage #107)
• reduced potential for bugs (e.g. GetGlyphIndex sets a dictionary value and can fail LayoutFarm/Typography#223)

If I were to do this, I would go for source generators to increase speed and reduce memory usage. But this excludes F# and VB.

As long as there is a type which contains the info, then whether that is encoded to a file or to C# source code is an implementation detail.

I assume that the relevant information is to do with glyph sizing & positioning in the maths font?
