  Log Message:
  -----------
  [offload] add context to olMemAlloc* (#224930)

This is the last part of the context refactor. This patch:
  - Adds context param to all memory allocation functions.
  - Routes ptr info through the plugins instead of a global map.
  - Removes allocation tracking from liboffload.
- olGetMemInfo(OL_MEM_INFO_DEVICE) now returns INVALID_ARGUMENT for host
   allocations, which have no per-device affinity.
   
Re-land of #222677 + #224622, which were reverted together in #224703.
