* Enable relocation of the Project Game Release Layout
Relocating the Project Game Release Layout to another directory on the file system failed due to the querying of the engine root failing due to the ComponentApplication::m_engineRoot not using the project path stored in the SettingsRegisry if the engine root cannot be detected
Removed the ApplicationRequestBus GetEngineRoot function.
The ComponentApplicationRequestBus has a function of the same name that returns the same path.
Removed the deprecated GetAppRoot function.
The path it returns has no defined value. It was not the engine root or the project root.
Removed unused CFileUtil and CFileUtil_impl functions that were invoking the ApplicationREquestBus GetEngineRoot function.
On the way to update the functions it was discovered that they aren't called
Added a CalculateBranchToken overload that can populate a fixed_string to avoid heap allocations

The test was relying on immediate updates from the prefab system which are now scheduled for a later tick - this reworks the tests to wait for deferred updates before validating state

The EntityOutlinerListModel was violating the QAbstractItemModel contract in a few cases, as reported by `QAbstractItemModelTester`. The important ones causing issues were:
- Entry order was not guaranteed, leading to model indices pointing at invalid data
- Parent/child relationships could be temporarily invalid due to a change I made in EditorEntityModel::RemoveEntity to try to avoid an unnecessary reparent operation - as it turned out, the parent/child data was being cached even for recreated entities and not clearing child data could cause issues
- `EntityOutlinerListModel::ProcessEntityUpdates` was emitting data changed between two indices that didn't necessarily share a parent, which is [undefined behavior](https://doc.qt.io/qt-5/qabstractitemmodel.html#dataChanged)
The other reported issues (that weren't really causing issues with `QTreeView`) were:
- The root index had flags other than `Qt::ItemIsDropEnabled`
- `rowCount` showed all columns as having children
- `parent` showed indices as being parented to a non-0 column
This change introduces fixes for the above issues, namely:
- Reverts my change to `EditorEntityModel::RemoveEntity` to ensure we don't have invalid parent/child references sitting in the cache
- Ensures `EditorEntityModelEntry` child ordering is guaranteed sorted by EntityId, to prevent the `EntityOutlinerListModel` from having indices pointed at invalid data*.
- Fixes various model sanity issues, such as `rowCount` being 0 for indices with a non-0 column
Two unit tests were added to reproduce the invalid behavior and validate the fix: TestCreateFlatHierarchyUndoAndRedoWorks and TestCreateNestedHierarchyUndoAndRedoWorks
This change focuses on correctness over performance. My subjective in-Editor outliner experience is about the same, but it may be worthwhile to expand the test coverage with a benchmarking suite to look into areas for optimization.
*As a rough illustration of the previous child ordering behavior, consider the following entity hierarchy:
```
Root (EID 9999)
|_ Child1 (EID 2)
|_ Child2 (EID 3)
|_ Child3 (EID 4)
```
With an representations like the following pseudocode:
```
// EditorEntityModel representation
EditorEntityModelEntry root;
root.children[0] = 2;
root.children[1] = 3;
root.children[2] = 4;
// EditorOutlinerListModel representation
// row, column, user data (64 bit uint)
child1 = QModelIndex(0, 0, 2)
child2 = QModelIndex(1, 0, 3)
child3 = QModelIndex(2, 0, 4)
```
When removing a child, the `EditorEntityModel` used to do roughly the following:
```
// Swap and pop the last child
int indexToRemove = 0;
swap(root.children[indexToRemove], root.children[root.children.size() - 1]);
root.children.resize(root.children.size() - 1);
model.notifyRemoved(root, indexToRemove); // model removes the row indicated
// Leading to this EditorEntityModel state
root.children[0] = 4;
root.children[1] = 3;
// And this EntityOutlinerListModel state, note that the row indices are swapped from the indices in the backing storage
child2 = QModelIndex(0, 0, 3)
child3 = QModelIndex(1, 0, 4)
```
A QModelIndex having a row that doesn't match its underlying data is undefined behavior, and was the source of an intermittent crash in our `QSortFilterProxyModel` as subsequent updates to the wrong row led to an invalid proxy state.
