Remove context locks from visualization commands (#7953 )

It looks like visualization commands had required context lock unnecessairly. Context manager methods are synchronized and therefore should not need the lock before submitting a correspodning background job.

Additionally, the presence of a context lock leads a deadlock:
1. Consider a long running execution of a program that does not finish within the 5 seconds
2. In the meantime there comes either an `AttachVisualization` or `DetachVisualization` request from the client

The latter will get stuck and eventually timeout out because it cannot acquire the lock withing the required time limits. It is still possible that a single long-running `ExecuteJob` might block other ones (including visualization ones) but that's a separate work.

Fixes some issues present in #7941.

# Important Notes
We need to still investigate `ExecuteJob`s need for context lock which might delay the execution of other background jobs that require it as well (mostly concerned about visualization).

Enso Language Server

The Enso Language Server is responsibile for providing a remote-communication protocol for the runtime, exposing many of its features to the users. In addition it provides the backing service for much of the IDE functionality associated with the language. It encompasses the following functionality:

Introspection Services: Giving clients the ability to observe information about their running code including values, types, profiling information, and debugging.
Code Execution: The ability for clients to execute arbitrary Enso code in arbitrary scopes. This can be used in conjunction with the above to provide a REPL with an integrated debugger.
Code Completion: Sophisticated completion functionality that refines suggestions intelligently based on context.
Node Management: Tracking and providing the language server's internal node representation of the Enso program.
Code Analysis: Analysis functionality for Enso code (e.g. find usages, jump-to-definition, and so on).
Refactoring: Refactoring functionality for Enso code (e.g. rename, move, extract, and so on).
Type Interactions: Features for type-driven-development that allow users to interact with the types of their programs.
