fix(runtime-core): fix SSR memoery leak due to props normalization cache

fix #2225

The previous props/emits normlaization was caching normalized result per
app instance, but during SSR there is a new app instance created for
every request.

The fix now de-opts props/emits normlaization caching when there are
props/emits declared in global mixins - which is a very rare use case.

perf: do not enable hmr in non-browser envs
