feat(amazonq): Move inline completion to Flare (#7480)

## Problem

https://github.com/aws/aws-toolkit-vscode/pull/7450/files is too
convoluted, hard to review and we also found a couple of regressions.

## Solution

Move inline completion to Flare first in this PR. Then we plan on how to
move auth to Flare. After this merge,
https://github.com/aws/aws-toolkit-vscode/pull/7450/files will be a lot
easier to debug and review.
