Streamline the forked AwsLambdaInstrumentation (packages/aws-serverless/src/integration/instrumentation-aws-lambda/) to the SDK's needs in four steps:

1. Improve test coverage for the parts of the instrumentation the SDK uses.
2. Clean out unused parts, relying on the tests from step 1 to catch regressions.
3. Remove the /* eslint-disable */ and make the files pass the linter if possible without breakage.
4. Replace otel tracer API calls with Sentry API calls, folding the requestHook (origin/op) and responseHook (captureException) wired in from awslambda.ts into the instrumentation.
