Add current-process debug port access

[penalosa]

Summary

• add current() to the workerdDebugPort binding
• route it through an in-process WorkerdDebugPort capability without opening a TCP connection
• retain the existing connect(address) behaviour for remote workerd processes

Testing

• just format
• bazel test //src/workerd/server:server-test@ --nocache_test_results --test_output=errors (cancelled before execution; relying on CI)
