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
        memorySize: 1769
        timeout: 28 # in seconds (API Gateway has a timeout of 29 seconds)
        runtime: php-82-fpm
        events:
            - httpApi: '*'

constructs:
    website:
        type: server-side-website
        domain: ${param:domain}
        certificate: ${param:certificate}
        assets:
            '/assets/*': public/assets

After

functions:
    web:
        handler: public/index.php
        memorySize: 1769

        runtime: php-82-fpm
        url: true

constructs:
    website:
        type: server-side-website
        domain: ${param:domain}
        certificate: ${param:certificate}
        originName: web
        assets:

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)
