Core: Exclude callbacks & deferred modules in the slim build as well.

mgol · mgol · commit 4112512330dc · 2019-12-02T19:59:50.000+01:00
So far, the slim build only excluded ajax &amp; effects modules. As many web apps
right now rely on native Promises, often with a polyfill for legacy browsers,
deferred &amp; callbacks modules are not that useful for sites that already exclude
ajax &amp; effects modules.

This decreases the gzipped minified size of the slim module by 1758 bytes,
to 19656 bytes (below 20k!).
