[mac-frame] helper methods to copy ExtAddress in normal/reverse byte order (#4144)

Browse Source 
This commit updates `Mac::ExtAddress` and `Mac::Address` to add
helper methods to copy address from/to a byte array in normal or
reverse bye order. This commit also adds a unit test for the two
Address classes.
