This patch adds the ability to return a `LogicalPlan` by value from a
`TableProvider`.
## Rationale for this change
Let's assume that we have `TableProvider` that supports concurrent
modifications of the inner logical plan (for example, mutable VIEW), and it
cannot afford to provide a reference.
It is implied that code requiring only a clone (such as `inline_table_scan`)
will use the newly added method.

## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?

## Are there any user-facing changes?
One can return `LogicalPlan` by value from `TableProvider`, if cannot return
a reference for some reason.
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.
