feat: Add timeouts block for vpc origin resource

[Ichigo97438]

Description

Adds timeouts configuration for vpc origin resource.

resource "aws_cloudfront_vpc_origin" "this" {
  for_each = local.create_vpc_origin ? var.vpc_origin : {}

  vpc_origin_endpoint_config {
    name                   = each.value["name"]
    arn                    = each.value["arn"]
    http_port              = each.value["http_port"]
    https_port             = each.value["https_port"]
    origin_protocol_policy = each.value["origin_protocol_policy"]

    origin_ssl_protocols {
      items    = each.value.origin_ssl_protocols.items
      quantity = each.value.origin_ssl_protocols.quantity
    }
  }

  timeouts {
    create = try(var.vpc_origin_timeouts.create, null)
    update = try(var.vpc_origin_timeouts.update, null)
    delete = try(var.vpc_origin_timeouts.delete, null)
  }

  tags = var.tags
}

Motivation and Context

Solves #163
VPC Origin creation can be longer than default terraform timeout, which stops deployments and forces to manually untaint resource before continuing deployment.
This PR adds an optional timeout configuration in the vpc_origin variable and uses this configuration in the aws_cloudfront_vpc_origin resource.

ah, this module still supports Terraform 0.13.x which means we won't be able to use variable optional attributes (1.3+)

we'll have to wait to take a breaking change to update

@bryantbiggs
I created a new variable vpc_origin_timeouts instead so as to not use optional and avoid breaking changes.

Hi @bryantbiggs!
The latest pipeline failed because of an issue in module ec2 (terraform-aws-modules/terraform-aws-ec2-instance#434).
It is not related to the changes in this pull request.

Can this pull request still be merged or should changes be made to versions.tf file to force the aws provider version following the quick fix mentioned in the issue?
