Wire up createViewTransitionInstance and suspendOnActiveViewTransition in Fabric

[zeyap]

Summary

• Wires up the native fabricCreateViewTransitionInstance call in createViewTransitionInstance which will create a ShadowNode for old pseudo element
• Extracts tag allocation logic into a shared allocateTag() function exported from ReactFiberConfigFabric
  • Imports allocateTag in ReactFiberConfigFabricWithViewTransition
  • Reuses allocateTag() in createInstance and createTextInstance instead of inline tag incrementing
• Wires up native fabricSuspendOnActiveViewTransition call in suspendOnActiveViewTransition which suspends another view transition when the previous one is not yet finished

Test plan

• Existing Fabric renderer tests should continue to pass
• ViewTransition instance creation now properly allocates a tag and calls the native module
