[Android] Add --unmap-all to forwarder2.

[Android] Add --unmap-all to forwarder2.

In some scenarios (e.g., single-device restart), we want to unmap all
ports forwarded from a given device up to the host and clear the existing
cached adb port for that device. We want to be able to do this even if
the calling process doesn't know all of those ports. This change adds
the --unmap-all command to forwarder2 to support such use cases.
