Rename "hasActiveCatalystInstance" to "hasActiveReactInstance" for clarification

Summary:
Sometimes ```hasActiveCatalystInstance()``` is used to check if it's safe to access the CatalystInstance, which will still crash in Venice.

Previously we mitigate this by changing ```reactContext.hasActiveCatalystInstance()``` to ```reactContext.hasActiveCatalystInstance() || reactContext.isBridgeless()```.

To solve this for all and good the plan is:
1, Rename ```hasActiveCatalystInstance()``` to ```hasActiveReactInstance()``` so it won't sounds like CatalystInstance-only.
2, Implement hasActiveReactInstance() for Venice. D27343867
3, Remove previous mitigation. D27343952

This diff is the first step, by xbgs there are **58** non-generated callsites of  ```hasActiveCatalystInstance()``` in code base which are all renamed in this diff.
