Subject: [PATCH] [aws-lambda] Add protocol to APIGatewayRequestContext.
 (#42419)

Fixes #42049.

No decent docs from AWS for the actual proxy integration, on the
Lambda side or the API Gateway side, but there's an approximation on
the API Gateway docs for the VTL $context variable:

https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html#context-variable-reference

From experimentation, not all of the variables referenced above exist,
at least most of the time, but everything except the `protocol` that
was present in what I received already existed.
