ec2_ami_copy: add tag_equality option for idempotence using tags (#40088)

* Allow idempotent use of ec2_ami_copy

When `tag_equality` is set true, use tags to determine
if AMIs in different accounts are the same, and don't
copy the AMI twice if they are the same.

Use AnsibleAWSModule and make imports more consistent
with other modules

* Update version added

* More code review changes

* Review changes - Recommended way to start EC2 connection
