New custom activity object

The platform API will support the Emails & Activities (E&A) app in API versions 2024-10 and later. We added the following queries to read, create, and delete custom activities in the E&A app:

• custom_activity query
• create_custom_activity mutation
• delete_custom_activity mutation

mutation {
  create_custom_activity (color: SLATE_BLUE, icon_id: TRIPOD, name: "Test custom activity") {
    id
  }
}
