Implement selective syncing in the pull dialog

[sejas]

Related issues

• Fixes STU-620

Proposed Changes

• Studio changes to pull dialog to render the remote file tree using the latest backup.
• The pull will generate a new fresh backup anyway.
• Jetpack Imports now use merge strategy.

Testing Instructions

Test the new flow pulling the latest rewind_id

• Apply the PR 188955-ghe-Automattic/wpcom if not deployed yet in your sandbox.
• Make sure you have some files in mu-plugins and/or fonts in your remote site.
• Run npm start.
• Connect to your remote site.
• Click "Pull".
• Select "Specific files and folders" dropdown
• Observe the tree can be inspected deeply and async
• Confirm the pull.
• Wait until the pull finishes.
• Open Finder.
• Observe that the selected files and folders are restored correctly.

Try pulling a site without backups

• You can use backend production , so the rewind_id fails
• Click pull
• Observe the checkboxes are disabled

Test Studio other backups

• Try importing other backup formats, like Playground, Local, or wpress
• Confirm they work as expected

Thanks for addressing feedback 👍
It works perfectly, I tested that rewind_id is used correctly with manually adding file to fonts folder, pushign it then opening Pull dialog and checking that I don't see it, but after updating backup it appeared. Also tested pulling separately plugins, fonts, and all files, and every time it worked as expected. Also tested importing backups: locals, wpress, playground and jetpack - everything works well 👍

Regarding code I have some feedback and things to discuss.

I haven't finished figuring out all the code around sync store, but I am thinking - would it be less code and woudl it be more clear and simple code if we use react-query here? I have feeling that redux here is redundant.
WDYT?

I addressed all the feedback above, thanks for the great suggestions.

About react-query vs redux, I think we shouldn't introduce a new library in this PR, and we should discuss it as a team.
I like TansStack Query, but since we decided to use RTK Queries I think we should keep using them.
