Encode FontPath data into an ArrayBuffer

[ryzokuken]

Serialize FontPath commands into a binary format
and store it in an ArrayBuffer so that it can
eventually be stored in a SharedArrayBuffer.

This PR is along the same lines as #20197 and #20340

For the glyph paths, we should use the same format as "described" here:

pdf.js/src/display/canvas.js

Lines 1491 to 1520 in d83cbb2

	if (!(path instanceof Path2D)) {
	// Using a SVG string is slightly slower than using the following loop.
	const path2d = (data[0] = new Path2D());
	for (let i = 0, ii = path.length; i < ii; ) {
	switch (path[i++]) {
	case DrawOPS.moveTo:
	path2d.moveTo(path[i++], path[i++]);
	break;
	case DrawOPS.lineTo:
	path2d.lineTo(path[i++], path[i++]);
	break;
	case DrawOPS.curveTo:
	path2d.bezierCurveTo(
	path[i++],
	path[i++],
	path[i++],
	path[i++],
	path[i++],
	path[i++]
	);
	break;
	case DrawOPS.closePath:
	path2d.closePath();
	break;
	default:
	warn(`Unrecognized drawing path operator: ${path[i - 1]}`);
	break;
	}
	}
	path = path2d;

Using a SVG string is slightly slower and using this binary data would help to make the serialization a bit simpler.

Thanks for the comments, @calixteman @timvandermeij they should be addressed now PTAL.
