trace: ipc_logging: Add QTimer timestamp alongside kernel timestamp

IPC Logging currently displays the kernel log timestamp, which is based on
a timer that does not increase when the Apps processor is in suspend. This
means that the kernel log timestamp "loses time" and cannot be correlated
with events on other processors. The source of the QTimer timestamp is
always running and has the same source as other logs in the system, which
makes it convenient to correlate logs across the system.

In IPC Logging, display the QTimer timestamp next to the kernel timestamp
to make it easier to correlate logs across the system. Increase the IPC
Logging version to 2 to enable compatibility with tools that extract the
logs from memory dumps.
