Feature/Pixel density and scale (#2757)

* Feature/Pixel density and scale

Add new parameters to VideoStreamingCapability structure:
- diagonalScreenSize - diagonal screen size of the screen;
- pixelPerInch - Pixel per inch (PPI) of the screen;
- scale - Scale value to determine how the app should scale
the captured view.

Add new parameters with default values to hmi_capabilities.json:
- diagonalScreenSize
- pixelPerInch
- scale

* Add min and max value for "scale" parameter.

Add min and max values for parameter scale in Structs index for
VideoStreamingCapabilities struct.
