Feature: Improving Performance, optimizations, reliability and codebase

[d2dyno1]

Is your feature request related to a problem? Please describe.
A large number of users have been recently complaining over the performance, optimization and reliablity with Files. These requests haven't been really addressed before (at least taken with enough seriousness).

Describe the solution you'd like
These problems really should be taken care of. We should start with upgrading the codebase and its structure. This will help us later to work with it and solve performance issues.

Additional context
Since a new update just dropped we have more time now to work on some of the backend stuff.

Please reference this issue in every PR that focuses on optimizations to keep track of the progress.

• Home page, favorites and drives
• Thumbnails
• Startup performance
• Deleting large batches of files
• Less than 1% crash rate
• Improve performance when resuming multiple tabs from the background (restoring multiple tabs is visibly slow)
• Improve ram usage

We're excited to share that startup performance will be significantly improved in the upcoming release of version 3. You can download the preview version from our website https://files.community/download.

The performance issues in Git repos has been resolved in our dev branch and will be included in the next release.

Thumbnail performance is better in the dev branch, but we're still trying to fix the issue with loading a lot of thumbnails simultaneously in the Grid View layout. In the meantime, turning off the option to show thumbnails helps as a workaround for this issue.
