perf: add inline debug logs (#8017)

## Problem

the debug string is missed somehow  and not being logged

```
let msg = indent(
                `codewhisperer: request-id: ${requestId},
                timestamp(epoch): ${Date.now()},
                timezone: ${timezone},
                datetime: ${new Date().toLocaleString([], { timeZone: timezone })},
                vscode version: '${vscode.version}',
                extension version: '${extensionVersion}',
                filename: '${EditorContext.getFileName(editor)}',
                left context of line:  '${session.leftContextOfCurrentLine}',
                line number: ${session.startPos.line},
                character location: ${session.startPos.character},
                latency: ${latency} ms.
                Recommendations:`,
                4,
                true
            ).trimStart()
```
