Run test262 tests from a git submodule

Instead of an in-tree checkout use a git submodule of test262 so we can
pin the tests to a particular commit and pull in updates when we are
ready for them.

Requires some changes in various paths.

The tests that were currently marked as expected to fail were not added
to upstream test262 yet, so they are removed from expected-failures.txt.
