[macOS] Battery check in platform_channel sample (#123354)

Browse Source 
Adds a check for the case where a device has no battery present. The
devicelab test expects the text "No battery." in the case where a device
has no battery. This is triggered by returning an error with a
NO_BATTERY error code.

Also applies some cosmetic fixes:
* Amends a copyright notice to Flutter instead of com.example
* Deletes an unused test.
