[fix_encoding] Remove fix_encoding

The fix_encoding module within depot_tools was included back in the python2[1] days to as a be all encoding fix boilerplate that is called across depot_tools scripts.

However, now that depot_tools officially deprecated support for py2 and support >= 3.8[2], the boilerplate is not needed anymore.

* `fix_win_codec()`[3] The 'cp65001' codec issue this fixes is fixed in python 3.3[4].
* `fix_default_encoding()`[5] python3 defaults to utf8.
* `fix_win_sys_argv()`[6] sys.srgv unicode issue is fixed in python3[7].
* `fix_win_console()`[8] Fixed[9].
