This CL adds:
- a new function `with_memory_space_constraint` that allow to add
a memory space constraint on a Pallas call input.
- `HBM` enum value for Pallas TPU memory spaces
This CL only supports HBM and VMEM at the moment. In general these annotations only work on TPU because the mechanism that enforces them is only present in XLA TPU.
