core: move fn to the syntax tier

Browse source 
fn -> fn* is a one-line head-swap (the analyzer treats fn* as the primitive). It's
in 00-syntax since the analyzer, kernel, and other overlay macro bodies all use fn.
First of the fundamental macros to move.

conformance 228x3, fixpoint, clojure-test-suite 3930.
