refactor(amazonq): deprecate codewhisperer context utils (#7241)

## Problem
deprecation for inline

## Solution
deprecates:
1. supplemental context + its tests, since that was only passed into
codewhisperer
2. codewhisperer coverage tracker, since thats [already in
flare](https://github.com/aws/language-servers/blob/main/server/aws-lsp-codewhisperer/src/language-server/inline-completion/codePercentage.ts)
3. [classifier
trigger](https://github.com/aws/language-servers/blob/main/server/aws-lsp-codewhisperer/src/language-server/inline-completion/auto-trigger/coefficients.json),
since that's in flare
4. inlineCompletionProvider is no longer used and should have been in my
other PR
5. editorContext utils, since that was used with supplemental context
