Summary: SPMD expects the mesh to be the same across the board. Therefore, introduce the concept of a global mesh to reduce the need to carry the same mesh in the code. Test Plan: python test/spmd/test_xla_sharding.py -v -k test_global_mesh

Looks great, thanks for adding this Jiewen!
Do you want to add a section to the spmd.md doc about the usage? It could be useful to explain why a global mesh is needed. (I'll also take an AI to update our resnet example to use a single mesh across the program)

Thanks for the quick review, Jon. Let me do the doc update later. I'm in a rush... |

Let's ignore the GPU test given it takes forever. I'm in a very tight deadline. |
