Run task first and detect local execution

[troychiu]

Tracking issue

flyteorg/flyte#4284

Describe your changes

This PR introduces two enhancements to the Flyin VSCode decorator:

1. Conditional VSCode Server Launching: The VSCode server launch behavior is now context-sensitive:

• Local Execution: When a task is executed locally (using commands like python xxx.py or pyflyte run xxx), the VSCode server will not be initiated.
• Remote Execution: In contrast, when a task is run remotely (using pyflyte run --remote ...), the VSCode server will be launched.

2. New Argument - run_task_first: A new argument has been added to the decorator:

• Functionality: When set to True, this argument ensures that the user's task is executed first.
• Server Launching Condition: The VSCode server will only be launched if the user's task execution fails.

Check all the applicable boxes

• I updated the documentation accordingly.
• All new and existing tests passed.
• All commits are signed-off.
