We need to add UI test for "Encoding" menu to avoid regression.

For this purpose, I have created several methods in automation API.
They can be used for the above UI tests.

1 get the current used encoding name of the page in the specified tab.
2 get value of the encoding auto detection option.
3 enables and disable the encoding auto detection.
4 use the specified encoding to override the encoding of the page in the
 specified tab.

BUG=5515

The corresponding UI test is coming soon
