feat(ec2): implement IPeer to PrefixList to be usable as a connection peer

[Tietew]

Issue # (if applicable)

Closes #33607.

Reason for this change

When we want to add a security group rule with PrefixList as a connection peer,
we should write redundant prefixList:

const pl = new ec2.PrefixList(this, 'PrefixList', { ... });
instance.connections.allowFrom(ec2.Peer.prefixList(pl.prefixListId), ec2.Port.XXX);

This PR allows us to write DRY:

const pl = new ec2.PrefixList(this, 'PrefixList', { ... });
instance.connections.allowFrom(pl, ec2.Port.XXX);

Description of changes

• Modify the IPrefixList interface to extend IPeer
• Implement the required IPeer methods in PrefixListBase

Describe any new or updated permissions being added

Nothing

Description of how you validated changes

Added unit tests and updated an integ test.
