AWS::Serverless::HttpApi does not support DisableExecuteApiEndpoint

[kmkale]

Description:
CloudFormation resource AWS::ApiGatewayV2::Api supports the DisableExecuteApiEndpoint property. But the AWS::Serverless::HttpApi resource does not.

This property is useful when using custom domain with the api. Especially when using the new MTLS feature.

Steps to reproduce the issue:

1. Add DisableExecuteApiEndpoint: true to properties of a Type: AWS::Serverless::HttpApi resource in template.yaml
2. Run sam validate

Observed result:
$sam validate
Template provided at '/path/to/template.yaml' was invalid SAM Template.
Error: [InvalidResourceException('HttpApi', 'property DisableExecuteApiEndpoint not defined for resource of type AWS::Serverless::HttpApi')] ('HttpApi', 'property DisableExecuteApiEndpoint not defined for resource of type AWS::Serverless::HttpApi')
Expected result:
AWS::Serverless::HttpApi resource supports the DisableExecuteApiEndpoint property, validation and deploy succeeds.

We will release #1725 to support it.

Getting this error when trying to use it now as soon as I set DisableExecuteApiEndpoint: True in my SAM template
