refactor(amazonq): deprecate amazon q inline through vscode

[jpinkney-aws]

Problem

• we're moving to inline via flare

Solution

• deprecate amazon q inline

Notes

deprecation steps:

1. removed recommendation handler and recommendation service and all regular dependencies, since those are the bulk of inline suggestions
2. removed command registrations for onacceptance
3. removed tests that are no longer relevant to the vscode implementation since they are already in flare
4. modified the lineAnnotationController and activeStateControllers to comment out any missing imports, since those still need to be there in the new implementation
5. removed pagination calls, since those are now done through flare
6. remove keystroke handler, since that's now done by the vscode api
7. removed old cloud9 compatability code for inline

Future PRs:

• Refactor lineAnnoationController and activeStateControllers
• re-implement the aws.amazonq.refreshAnnotation command
• fix the inline e2e tests, since now they will fully go through flare instead of the recommendation handler
• fix any unit tests that are now failing
• updating the status bar when a request is in progress
