fix: Add egress rule update support

[renebarbosafl]

Description

This PR complements https://github.com/terraform-aws-modules/terraform-aws-route53/pull/106 by adding a new variable, allowing the submodule to update egress rules. This PR also adds support for setting static IP address on the resolver endpoint instances.

Motivation and Context

The previous pull request was hardcoding an egress rule allowing All the traffic. Users could want to update these rules as their needs and it's also a security issue.

Breaking Changes

The default value for of var.security_group_egress_cidr_blocks is an empty list, it can cause problems when using inbound resolver-endpoints and not declaring this variable. To fix it, we can do something like:

security_group_egress_cidr_blocks = [
  "0.0.0.0/0" # Allow All
]

or

security_group_egress_cidr_blocks = [
  module.vpc2.vpc_cidr_block # Allow target vpc
]
