Reconciler: Combine identical cases in findParent

[OnlyWick]

Summary

When lookup Parent, HostRoot and HostPortal should be merged, because when creating a Portal, it will also include containerInfo(So we can directly use this containerInfo to delete the real DOM nodes.), so there is no need to handle them separately.

How did you test this change?

No behavior changes, all existing tests pass.

[OnlyWick]

Based on the code I am currently debugging, HostRoot and HostPortal have some commonalities.

see below code:

react/packages/react-reconciler/src/ReactFiberCommitHostEffects.js

Lines 408 to 414 in 221f300

	case HostRoot:
	case HostPortal: {
	const parent: Container = parentFiber.stateNode.containerInfo;
	const before = getHostSibling(finishedWork);
	insertOrAppendPlacementNodeIntoContainer(finishedWork, before, parent);
	break;
	}

react/packages/react-reconciler/src/ReactFiberCommitWork.js

Lines 4860 to 4873 in 221f300

	case HostRoot:
	case HostPortal: {
	if (supportsResources) {
	const previousHoistableRoot = currentHoistableRoot;
	const container: Container = fiber.stateNode.containerInfo;
	currentHoistableRoot = getHoistableRoot(container);
	recursivelyAccumulateSuspenseyCommit(fiber);
	currentHoistableRoot = previousHoistableRoot;
	} else {
	recursivelyAccumulateSuspenseyCommit(fiber);
	}
	break;
	}

Can you edit your PR top comment to contain a description of what is changing and why?

[OnlyWick]

@gnoff Done, I haven't done more exploration on Portal yet(But the code here does feel a bit redundant, because Portal has a containerInfo property, and it is a container.)
