feat(ocap-kernel): Implement hierarchical logging

[grypez]

Closes: #217

This PR constitutes the majority of the lift for the referenced logging ticket.

@metamask/logger

• implements a protocol for serialized transfer of log entries over a @metamask/streams DuplexStream
• adds the injectStream method to the Logger for subscribing to logger notifications
• adds makeArrayTransport which returns a transport which appends log entries to the supplied array argument

@metamask/ocap-kernel

• The logger passed to the Kernel constructor is plumbed to subcomponents all the way to the vat user code's console endowment and logger power.

@ocap/kernel-test

• no longer relies on intercepting process.stdout to assert expected test vat operations
• utilizes logger tags for distinguishing different vat operations

btw I noticed that the log methods (log, debug, info, etc.) are created using function binding but aren't hardened. We should alter the constructor of the Logger like so:

const bind = (level: LogLevel): LogMethod => 
    harden(this.#dispatch.bind(this, {
      ...this.#options,
      level,
    }) as LogMethod);

Thought this will probably brake some tests, so we should use the mocked SES environment there
