Add support for updating CLR and deploy app using serial port

[josesimoes]

Description

• Add options to update nano device connected to serial port.
• Move (and rename Esp32ClrFile to ClrFile) to allow reuse from all platforms.
• Update code accordingly.
• Improve all methods connecting to nano device so that device watchers aren't started anymore and a specific serial port is used.
• Add fwVersion and clrFile parameters to UpdateDeviceClrAsync. Implement support for those.
• FirmwarePackageFactory now accepts fwVersion parameter.
• Clean-up code in FirmwarePackageFactory and add missing license header.
• Update README with new options to update nano device using serial port.

Motivation and Context

• Allow updating the CLR and deploying an application using the Wire Protocol port instead of a dedicated connection (JTAG or JLink).
• Get the connected device details using the Wire Protocol port.
