The main reason for this change is that the new API
actually checks for every path whether it's a leaf.
This prevents a bug when we first mark a path as expanded
and then later we add it, so it shows as collapsed
(because it's newly added), but can't be expanded either
because the tree thinks it's expanded. An example
of this is the filtering tree, which tries to re-expand
every expanded path after refiltering, even those paths
that don't exist because of that refiltering.
A nice side effect is a considerable performance improvement
in case there are many expanded paths.

1. JupyterClearCellOutputAction now will work with both editor and outputs if the outputs will provide proper interval.
2. Web outputs (not markdown, but web) will have now their personal popup menu with only one action "clear".

Otherwise, we end up with dozens of unintentionally public names such as "s", "i", "k"
even in the standard library (e.g. `this.s` or `pickletools.i`).
Ideally, we should rely on .pyi stubs and the content of `__all__` to offer only explicitly
exposed API, but not every module has any of those two, and it's not clear how to match
.py files and the corresponding .pyi stubs fast enough for completion.

Previously, such names were visible only on so-called "extended" completion,
activated when the hotkey for the basic completion was hit twice. The main reason
was that collecting such variants from indexes was a slow process, and we
didn't want to harm the responsiveness of completion for basic names.
Now it becomes possible thanks to a number of performance optimizations:
* Instead of using three separate indexes for classes, functions and variables,
we use one -- PyExportedModuleAttributeIndex. By definition, it includes only top-level
"importable" names, so we additionally save time by not filtering out irrelevant
entries. Also, it doesn't contain private definitions starting with an underscore.
It might bother some users, but given that the previous completion was used
extremely rarely, and the new one is going to be visible everywhere, it seems
that pruning unlikely entries as much as possible is a fare tradeoff. In the future,
we might enable them back on the "extended" completion if there is a demand.
Also, this index binds its keys to the project (`traceKeyHashToVirtualFileMapping`),
further eliminating useless index lookups.
* Thanks to the recent fixes in the platform (IJPL-265), it's now possible to
simultaneously iterate over all keys in an index and request values for a given key
without deadlocks, which is much faster than eagerly fetching all keys first.
* While scanning through all matching entries from indexes, we terminate
the lookup if the number of items exceeds the size of the lookup list.
We can further reduce this number by adjusting the "ide.completion.variant.limit"
registry value.
* Calculating expensive "canonical" import paths (e.g. "pkg.private.Name" is importable as
"pkg.Name") is offloaded to a background thread thanks to the `withExpensiveRenderer` API.
We still calculate these paths synchronously, though, for names whose raw qualified names
contain components starting with an underscore to decide whether these private names are
publicly re-exported and, hence, should be displayed.
The rest of the work has been put into reducing the number of entries on the list, e.g.
* The prefix under caret is now matched from the beginning of a name, e.g. `Bar<caret>`
matches `BarBaz`, but not `FooBar`.
* We don't suggest imported names clashing with those already available in scope.
* Some kinds of definitions are not suggested in specific contexts, e.g.
functions and variables are not suggested inside patterns and type hints.
* Nothing is suggested at the top-level of a class body, where dangling
reference expressions or calls are not normally expected.
Additionally, we don't suggest names from .pyi stubs at the moment, because
it pollutes the suggestion list with entries coming from the stubs for
third-party packages in Typeshed. We should probably enable them back once
we are able to properly disable Typeshed entries for not installed packages.
Some legacy forms of completion are left in the extended mode. In particular,
qualified names of classes are offered inside string literals only in this mode.
Also, module and package names are suggested only in the extended mode, because
top-level packages and modules are already suggested for the basic completion
by PyModuleNameCompletionContributor.
A few tests in PyClassNameCompletionTest were updated or removed entirely because
* we no longer suggest private names
* we no longer suggest names from private modules not re-exported in a public module
* we no longer suggest names clashing with those already available in scope
* prefix matching policy was changed to start at the beginning of an identifier
The whole feature can be disabled with the option "Suggest importable classes,
functions and variables in basic completion" in settings.
