feat(ec2): well-known port aliases (#29793)

### Issue # (if applicable)

None as far as I can tell

### Reason for this change

The web console lists commonly used ports when adding a rule to a security group, this aims to reproduce this simple quality of life shortcut. It can also help with code readability, and might save people from a typo

### Description of changes

* Add well-known static `Port` instances
  * Intersection of the AWS web console listed ports and the [IANA Service Name and Transport Protocol Port Number Registry](https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt)

### Description of how you validated changes

Compared the AWS web console values to the IANA list, and added a unit test to make sure the alias behaved properly
