Macro to generate feature tables for backend documentation with standardized assert functions

The table contains ONLY feature names, status icons, and descriptions. Code examples appear as separate sections below the table.

Usage:

use apalis_core::features_table;
features_table! {
    setup = "MemoryStorage::new();",
    TaskSink => supported("Ability to push new tasks", true),
    Serialization => limited("Serialization support for arguments. Only accepts `json`"),
    FetchById => not_implemented("Allow fetching a task by its ID"),
    RegisterWorker => not_supported("Allow registering a worker with the backend"),
}
