[fx][graph_drawer] Improve graph drawer coloring and tensor_meta handling (#58699)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/58699
Make `call_function`/`call_method` random colors based on their target name. This coloring is stable according to the name of the target. Also handle tensor_meta more elegantly for quantized types, including print q_scale/q_zero_point if they're used.
Test Plan: Tested locally
