EME: Fix the CDM File IO test when run using unprefixed EME.

EME: Fix the CDM File IO test when run using unprefixed EME.

This test was not registering the unprefixed event handlers, processing the
message as the correct type, or enabling required peristent storage capability.

The two FileIOTest tests may still not be testing both paths, but the prefixed
path will be removed in my next CL.

BUG=249976
TEST=ECKEncryptedMediaTest.FileIOTest passes when prefixed EME is manually disabled in the test.

media/test/data/eme_player_js/utils.js:178: var message =
String.fromCharCode.apply(null, Utils.convertToUint8Array(msg));
Since there is no way to assert that a Uint8Array was passed in, always do the
conversion.
