PicoVector: Add tracked memory alloc, track the node buffer.
...
With a low GC threshold the node buffer was being collected (despite guards against this)
and causing further drawing operations to be corrupted.
Add a new tracked malloc method and use it for node buffers and font data.
Tweak pp_poly_add_path to accept a point count, avoiding many successive rellocs when
dealing with a known quantity of points (copying from an af_glyph_t.)

PicoVector: AF: Support for 16bit point count.
...
Somewhere in the conversion from C++ to C we lost support for 16-bit point counts.
Raise the internal point count to 16-bit, and check for a flag in the font.
If the flag is set, treat the point count as 16-bits, otherwise fallback to 8 for back compatibility.

PicoVector: Avoid MicroPython GC.
...
Since we're not using tracked allocation, any memory we don't explicitly
hold a reference to will be assumed unused by MicroPython's GC.
Pass up the pp_nodes and pp_node_counts points (hackily) to fix this.

PicoGraphics: Layers.
...
Add preliminary support for multiple layered drawing surfaces.
Allows, for example, static content to be loaded into one layer and
remain unmodified while the above layer contains animations.
Particularly useful for drawing PNG or JPEG UI elements which are
then overdrawn with text or animated elements, without paying the
cost of loading/decoding every frame.

Add a simple check to discard any attempt to draw zero length spans.
