perf(core): preserve ops between snapshots (#18080)

This commit changes the build process in a way that preserves already
registered ops in the snapshot. This allows us to skip creating hundreds of
"v8::String" on each startup, but sadly there is still some op registration
going on startup (however we're registering 49 ops instead of >200 ops). 

This situation could be further improved, by moving some of the ops 
from "runtime/" to a separate extension crates.
