telemetry(amazonq): align flare/vscode codewhisperer_serviceInvocation metric (#7244)

## Problem
vscode keeps track of `codewhispererImportRecommendationEnabled` inside
of the `codewhisperer_serviceInvocation` event but flare doesn't

## Solution
add it before emitting telemetry, since this is purely a client side
feature
