giles 20ac0fe948 Spec eval-cond and process-bindings in render.sx (remove platform implementations) ...

eval-cond and process-bindings were hand-written platform JS in
bootstrap_js.py rather than specced in .sx files. This violated the
SX host architecture principle. Now specced in render.sx as shared
render adapter helpers, bootstrapped to both JS and Python.

eval-cond handles both scheme-style ((test body) ...) and clojure-style
(test body test body ...) cond clauses. Returns unevaluated body
expression for the adapter to render in its own mode.

process-bindings evaluates let-binding pairs and returns extended env.
