core: Stage 2 Task 2 tier 2b — compile reify (make-reified as a fn)

Completes the protocol machinery: make-reified joins protocol-dispatch/
register-method as a ctx-capturing clojure.core fn (install-stateful-fns!).
- make-reified-impl takes the EVALUATED {keyword fn} method map (a phm when
  compiled, struct/table when interpreted) and builds the reified object.
- reify macro passes the protocol NAME as a string; method map is an ordinary
  map literal evaluating to {keyword fn}.
- Removed make-reified's special-symbol? entry + handler arm, and dropped
  make-reified + reify from host_iface special-names + compiler
  uncompilable-heads.

reify now compiles and dispatches in both modes (single- and multi-method).
With tier 2a, the full protocol surface (defprotocol/extend-type/
extend-protocol/reify) compiles; defrecord still waits on deftype (tier 5).

Gate green: conformance 267x3, fallback-zero 31/5, bootstrap-fixpoint
stage1==2==3, self-host, staged-bootstrap, clojure-test-suite >=4034/67,
features 78/78, all unit + spec (protocols 7/7x3).
