Clarify Component field options when creating a new activity type

If CiviCase is enabled, when adding a new Activity Type you are prompted to select the Component. Current drop-down options are:

• Contact
• CiviCase

This is misleading because "Contact" actually means the activity type can be used to create a standalone activity OR create an activity within a case. Suggested improvements:
1. Relabel field from "Component" to "Usage"

2. Relabel options to:

• Contacts OR Cases
• Cases Only
