cli/command/context: remove deprecated types and functions

These functions and types are shallow wrappers around the context
store and were intended for internal use as implementation for the
CLI itself.

They were exported in 3126920af1 to be
used by plugins and Docker Desktop. However, there's currently no public
uses of this, and Docker Desktop does not use these functions. These were
deprecated in 95eeafa551 and are no longer
used.

This patch removes the deprecated functions as they were meant to be
implementation specific for the CLI. If there's a need to provide
utilities for manipulating the context-store other than through the
CLI itself, we can consider creating an SDK for that purpose.

This removes:

- `RunCreate` and `CreateOptions`
- `RunExport` and `ExportOptions`
- `RunImport`
- `RunRemove` and `RemoveOptions`
- `RunUpdate` and `UpdateOptions`
- `RunUse`
