Change the paragraph text layout callback to take glyphs

implementation of features like elision or letter spacing in a shared code.

Simplify glyph interface
...
The textlayout module does not need to impose the exact glyph struct layout.
This paves the way for glyph based rendering.

Add an paragraph layout helper function to the corelib textlayout

Add basic text layout module for use with the MCU
...
This is based on the unicode line breaking algorithm (uses crate for
that), which also supports forced line breaks. The shaping is generic,
so on the MCU side we can do without at first.
