Update TF and CMake files for mlir-hlo move

The parts of the XLA dialects that we use have moved to a new directory in tensorflow (soon to be a separate repo). This updates the TF submodule to pick up these changes (including some fixes since last time that unbreak the integrations build) and fix the CMake files to match. We no longer need the XLA cmake file at all. Just the MLIR HLO CMake file.
