Sébastien Stormacq d8ee71fc09 add support for LOCAL_LAMBDA_PORT / HOST(#557) ...

Allows users to define on which port the Local server listens to, using
the `LOCAL_LAMBDA_PORT` environment variable.

While being at it, I also added `LOCAL_LAMBDA_HOST` if the user wants to
bind on a specific IP address.

I renamed `LOCAL_LAMBDA_SERVER_INVOCATION_ENDPOINT` to
`LOCAL_LAMBDA_INVOCATION_ENDPOINT` for consistency.

### Motivation:

Addresses
https://github.com/swift-server/swift-aws-lambda-runtime/issues/556

### Modifications:

- When run outside of the Lambda execution environment, check for the
value of `LOCAL_LAMBDA_PORT` and passes it down to the Lambda HTTP Local
Server and runtime client.

- Add a unit test 

### Result:

```
LAMBDA_USE_LOCAL_DEPS=../.. LOCAL_LAMBDA_PORT=8888 swift run                  

2025-09-01T21:55:22+0200 info LambdaRuntime: host="127.0.0.1" port=8888 [AWSLambdaRuntime] Server started and listening
