[APM] Only fetch custom links for users with a valid license

[sorenlouv]

Fixes issue reported on Discuss where custom links result in an error for users on basic license.

Improvements:

• Only fetch custom links for users with a gold license or higher
• lazy load custom links when the action menu is opened
• Clean up TransactionActionMenu component by co-locating everything related to custom links in the CustomLinkMenuSection

Bug introduced in 7.10 by #77630

How to downgrade to basic license:

curl http://localhost:9200/_license/start_basic\?acknowledge=true -X POST -u admin:changeme

Are you sure this bug was introduced by this issue? I ask it because we only notify the usage when the POST API is called, not when the GET API is called to return all custom links.
