Use a falling block entity to improve client side performance of FloatingTextParticle (#4714)

Browse Source 
Performance tests show that this has a considerable client-side performance advantage over using players. In my local tests, using 1000 floating texts in a 10x10x10 area, I observed an FPS increase from 1.5 to 8.0.
