[perf] migrate slow operations to non-blocking calls

[pq]

We're doing a lot of long-running processing on the UI thread which is

1. hurting performance, and
2. spamming the logs (distracting users as in https://github.com/flutter/flutter-intellij/issues/7151, https://github.com/flutter/flutter-intellij/issues/7641 and https://github.com/flutter/flutter-intellij/issues/8083)

We've had issues safely making the change to use the prescribed ReadAction.nonBlocking APIs (see for example: https://github.com/flutter/flutter-intellij/issues/7792) so we'll want to proceed thoughtfully.

This issue will stand as a tracker for migrations.

Some resources:

• 📖 plugin docs
• 📖 ReadAction.java
