Also some improvements to detector info iterator. Note that I added an
index property. I see this as being particularly useful for users to get
away from the old instrument python API. i.e.

for item : component_info
    if item.index == component_info.source:
        break

L1 and l2 on DetectorInfo type. L2 also on iterator item as property

root and indexOfAny exposed

There are two big changes in this PR. The first is inspecting the what
specific Load algorithm was used and switching to that after the first
chunk is loaded (removes determining the specific loader for subsequent
chunks). The second is to remove the logs before accumulating the
chunks.

TableWorkspace has all columns editable by default. PeaksWS has all columns read-only by default.

Values in editable cells can be changed. Changes are reflected in the underlying WS with the correct type.

TWD Model uses same "allowed workspaces" idea as MatrixWorkspaceDisplay

Additionally fix the DirectILL* unit tests.

Re #24137

We subclass AxesImage so that it first resizes
the data to 4K, the resizes to the window size.
