Use Lambda URL as CloudFront origin

[kevincerro]

Closes brefphp/bref#1625

This PR is a draft for using Lambda URL as CloudFront origin domain
Please review and write your opinion about how we must handle logic about this

⚠️ Lambda URL limitation: using not urlEncoded queryParams will throw an exception
https://mywebsite.com/?SampleArg=Ky4gdyRYLiA0JSAMOWx9Iw==
X-Amzn-Errortype = InvalidQueryStringException

Pending:

• Protect Lambda URL using IAM
• Ensure backwards compatibility
• Ensure config is easy to understand
• Implement multiple scenarios
  • No custom domain: Lambda Function URL
  • Website: CloudFront -> Lambda Function URL
  • API: CloudFront -> Lambda Function URL

Configuration changes

Before

functions:
    web:
        handler: public/index.php

        runtime: php-82-fpm
        events:

Uploaded some changes @mnapoli

I didn't managed to pass ts-lint checks on utils/GetWebLambdaFunctions.ts after some hours, sorry 😢 .
( e.httpApi || e.http || e.alb not valid)
(Maybe something is wrong with AWS function events typescript definition)

@mnapoli Sorry for reviving an old PR, but what is pending for this to get to upstream?

Hey! No problem with the ping, I'm actually tracking this initiative in brefphp/bref#1625 (comment) and I've posted a new update.

TL/DR: that wouldn't work when using a VPC 😢 Also I've asked around and got no signal from AWS teams that they're considering adding support for VPCs.
