Workbench actions for Tree Fuzzy Search Toggle

[keerthivasansa]

Fixes #173866

• Associated Issue: Associate a keyboard shortcut with the new "Fuzzy Match" toggle button #173866
• The code is up-to-date with the main branch

Changes

• Registered Workbench actions to toggle the Fuzzy Search behaviour in the Explorer Search Menu.
• The actions can be mapped to keyboard shortcuts hence allowing the user to create a keyboard shortcut to toggle or switch to a specific find match type.
• The registered actions are:
  - Explorer: Toggle Find Match Type
  - Explorer: Switch to Fuzzy Find Match Type
  - Explorer: Switch to Contagious Find Match Type

Technical Changes

• Since the other commands in command palette are associated with focusing on views, no separate actions file was present for explorer category. Thus, I have created explorerActions.ts in vs/base/browser/actions/explorerActions.ts and registered the actions in it.
• A getter and setter for findMatchType was required in AsyncDataTree for this to be modified from an action. Async Data Tree was modified accordingly.

This needs reviews by team members, and I am not one. Pinging @joaomoreno

Thanks for your contribution! I have simplified it to become a simple toggle. 🍻
