[1/n InputDispatcher refactor] Rename getWindowHandleLocked

There are two overloded methods with name getWindowHandleLocked one of
which is actually used to get the updated value of the same WindowHandle
if exists.

This CL renames the method to avoid confusion:
From: sp<WindowInfoHandle> getWindowHandle(
				const sp<WindowInfoHandle>&handle);
To: sp<android::gui::WindowInfoHandle> getUpdatedWindowHandle(
		const sp<android::gui::WindowInfoHandle>& handle);

Bug: 367661487
Bug: 245989146
Test: atest inputflinger_tests
Flag: EXEMPT refactor
