Deploy to create (as opposed to update) a Lambda Function

A command should exist to package up the code from a workspace, and publish it to a new AWS Lambda Function. UI Details need to be figured out, but I suspect this would use a Web View.

* command should be accessible from the Command Palette, AWS Explorer (Lambda node context menu, maybe on the AWS Explorer buttons too)
* Inputs:
* Lambda Function Name
* Description
* Handler
* Runtime
* Timeout
* Memory
* Environment Variables
* IAM Role
* Enable/Disable AWS X-Ray
* VPC
* DLQ
* Concurrency
* Tags (case sensitive key-value pair)
* S3 Bucket to deploy with

Start by reviewing the existing AWS Explorer Lambda node and Command Palette command paths mentioned in the issue; no files or tests are identified. Define the create-function flow and completion criteria around packaging the workspace and exposing all listed Lambda configuration inputs.
