Writes to `socket` a JSON capture of the memory usage and the memory
bucket definition, as a well-formed UTF-8 string.
The socket is closed by the server after all the data is written into
it.
TODO(https://fxbug.dev/42073090): Document the schema of the JSON.
Sample output:

For size reasons:
- Processes and Vmos have an initial entry that contains the names of the the fields in
the rest of the entries.
- The names of the VMOs are an index into the VMONames array.
