Generalizes NetworkActivity so it can be used for sockets but also disk files.
The host/port data becomes a single location string prefixed with socket://
or file:// and we're not using the FD as the identifier anymore.
IOActivityMonitor is now used in three places:
- nsFileStreams for plain files
- TelemetryVFS for sqlite files
- nsSocketTransport & nsUDPSocket for UDP & TCP sockets
