Ajax: Deprecate AJAX event aliases, inline event/alias into deprecated

A new `src/deprecated` directory makes it possible to exclude some deprecated
APIs from a custom build when their respective "parent" module is excluded
without keeping that module outside of the `src/deprecated` directory or
the `src/deprecated.js` file.

Closes gh-4572

 - **deprecated**: Methods documented as deprecated but not yet removed.
 - **dimensions**: The `.width()` and `.height()` methods, including `inner-` and `outer-` variations.
 - **effects**: The `.animate()` method and its shorthands such as `.slideUp()` or `.hide("slow")`.
-- **event**: The `.on()` and `.off()` methods and all event functionality. Also removes `event/alias`.
-- **event/alias**: All event attaching/triggering shorthands like `.click()` or `.mouseover()`.
+- **event**: The `.on()` and `.off()` methods and all event functionality.
 - **event/trigger**: The `.trigger()` and `.triggerHandler()` methods. Used by the **alias** module.
 - **offset**: The `.offset()`, `.position()`, `.offsetParent()`, `.scrollLeft()`, and `.scrollTop()` methods.
 - **wrap**: The `.wrap()`, `.wrapAll()`, `.wrapInner()`, and `.unwrap()` methods.
