[flow] Convert all remaining $Shape to $Partial

Summary:
Following the Flow upgrade, I'm looking at replacing all usages of $Shape in our codebase. Context here.

This diff handles all remaining cases, which were automatically updated via flow-upgrade, and did not cause any type errors or require further changes.

Depends on D10084
