Enable/Disable whether a workflow considered a MCP tool or not

### Severity

P1 - Critical (Blocking production)

### MCP Server Creation Source

MCP Server in Logic Apps

### Describe the Bug with repro steps

Currently, if a workflow has an HTTP Trigger and HTTP response it is considerd an MCP Tool .

There are some scenarios where a customer may not want to expose that workflow as an MCP Tool. We need to provide the ability to enable/disable whether or not the workflow is a Tool.

This may require an app setting to be used under the hood

NOTE: Even if the workflow is not considered a tool, the customer may still want it enabled.
