Feature enhancement details

Continuing the work from #8918.
For p5.js 2.x, add an additional test suite for textToModel().

The tests cases should use the same test strings as the textToPoints() benchmarks, targeting a sampleFactor which yields the same number of points. The goal is gauge performance across the textTo___ functions.

Test coverage must include the following renderers (not applicable to 2D):

• WebGL
• WebGPU
