Proper SWO support for the Black Magic Probe

[ssimek]

Contains the following changes

• slight modification of the deployment model so the binary dependencies are included directly in the package, the same way they are in e.g. arm.device-manager extension
• something must have changed in the meantime with Electron, because the original prebuilt binaries seem to work on all platforms without recompilation
  • tested on macOS, Win and Linux (ARM64) - everything works except SerialPort on Windows ARM64, but that wouldn't work with the old approach just the same
• a new UsbSWOSource has been added that reads a raw bulk endpoint
  • it autodetects the probe based on productName and interfaceName, both can be overridden
