80830bbece MCU: Refactor the renderer in a LineRenderer 
The LineRenderer is going to be a public type which can be used
by the MCU board support to draw.
Right now, it is used by the old code

08fb9a9336 Fix instructions on how to build the mcu printer demo for the simulator 
With the simulator this still requires a regular main() entry point.
For some reason a feature test for i-slint-backend-mcu/simulator doesn't work,
but it works with the local feature.

77445e9dc5 text handling: simplify text_size signature 
We can calculate the line height in the common code, that doesn't need to be done in the backends.

38abeaec41 text handling: clean up font traits 
Separate the text shaping functionality from font metrics by having a
FontMetrics trait next to the TextShaper. AbstractFont is the combining
super trait. This allows eliminating the font height member from
TextParagraphLayout and improving the overall naming of fields and
types.

Finally, this prepares the API for composability of TextShaper for font
fallback handling.

3ce142344a text handling: cleanup 
Rename "byte_offset" in the Glyph structure to "text_byte_offset" to make
it clearer that this refers to the original text. Also added docs.

93b5eda82e text handling: simplify glyph data structure handling 
Replace the abstract glyph trait with a glyph struct. That way the text
layout code can operate properly on a struct with fields, instead of on
functions on a trait (some of which returning a mutable reference). The
input is a glyph with offset, advance, etc. - everything needed for the
layout and the output is a position along with the platform specific
glyph data.

99ea6db9d4 text handling: simplify shaper <> glyph relation 
Use the Glyph trait also for the byte offset handling, to avoid the use of
tuples.

5f52f18df4 mcu text handling: Add support for letter spacing 
This is implemented generically by adjusting the advances on the shape buffer, so that we can
use the same in the future in the GL backend.

b6e7db0221 Minor cleanup in the MCU text handling 
Replace the use of Option for the associated glyph type with a
struct that can later implement a trait.

cc1aad8ce9 MCU: fix panic in the renderer 
Sometimes, BorderRectangle clips can get negative if the intersection
of two rectangle leads to a rectangle that is smaller than the previous
rectangle, but because of floating point error while computing the max
position, the resulting clip may still be negative.
Add a small value to compensate that error

afb59cba29 mcu: fix popups not visibly closing 
When closing a popup, notify the platform window, so that the mcu
backend can remember that region and start the dirty region with it.

Also, free all the rendering cache items of deleted items, to avoid accidental re-use
when re-opening a popup.

70f3f50359 mcu: Add support for automatic font size detection

via SLINT_FONT_SIZES, but additionally look for Text/TextInput/Window elements
and extract any constant font sizes
found.

This makes it work out of the box with the printer demo.
