Add assets search and search submit commands

[wanglam]

Description

This PR enhances the global search functionality by adding two new capabilities:

1. Assets Search Command: Enables searching for dashboards and visualizations directly from the global search bar. Users can now quickly find and navigate to saved objects without leaving their current context.

2. Search Submit Commands: Introduces a new command type that executes when users press Enter in the search bar, providing a more intuitive way to perform search-related actions.

Key changes include:

• Added searchAssets function to search for dashboards and visualizations via the saved objects API
• Implemented GlobalSearchSubmitCommand interface for Enter-key triggered actions
• Enhanced the search bar UI to display submit command hints and handle Enter key events
• Updated global search service to support both regular and submit commands

what's the difference between registerSearchCommand and registerSearchSubmitCommand? would be nice to add comment to each of them

[ruanyl]

I don't seem to see where is this function called registerSearchSubmitCommand, did I miss anything?

[wanglam]

For now the only search submit command is in the dashboards-assistant repo. Will raise a new PR for adding an example for this new methods.

[ruanyl]

Can we specify the type of assets when searching? Right now it seems to search all types of saved object, can we specify type in the query? for example: @vis:test, this will search visualization with keyword test
