c939de06 - Move dependencies on Tensorflow under third_party/xla_client and torch_xla/csrc to use TSL where possible (#4717)

Move dependencies on Tensorflow under third_party/xla_client and torch_xla/csrc to use TSL where possible (#4717) * Move dependencies and headers on tensorflow to use tensorflow/tsl in third_party/xla_client This commit takes care of the 'trivial' dependencies on tensorflow that can easily be replaced with targets that XLA will have. A quick glance at the remaining TF targets/headers suggests that they are all related to XRT. * Update formatting * More TSL replacements under csrc * Update csrc/*.cpp to use TSL where possible, run clang-format * This reverts commit 2dc2b48535612e72d9cba4da124929c5686aa016. * More tensorflow:: -> tsl:: replacements in csrc * Remove accidental duplication of commented out test * Fix formatting in helpers.h * Fix formatting (actually this time)
