[XLA] First step in adding Literal slice classes, to improve interface safety

More specically:
* Introducing a new LiteralBase abstract base class that contains all immutable
methods of from the old Literal class.
* Introducing a subclass LiteralSlice to replace original LiteralView class.
LiteralSlice class is read-only and does not own Shape nor any buffer through
the Pieces. Change a number of callers to use LiteralSlice directly.
* Change Literal class to explicitly own the underlying Shape as well as owning
the underlying buffer via Piece.
* Conversion from Literal to LiteralSlice is now done via an implicit

Previously, xla::DeviceMemoryAllocator::Allocate returned a

Unfortunately we ~never got this right. Essentially all users of
Allocate() call it in a loop, and TF_RETURN_IF_ERROR within the loop.
If any of these allocations fails (mostly commonly, due to OOM), we leak
everything we've allocated up until then.

Better wrapping of stream executor's cuDNN API calls. Replacing mutex locking and setting the cuDNN stream followed by calling wrap::cudnn... with an RAII CudnnHandle object that handles the former two operations.
Distinguish three different API types:
A) APIs that don't take a cudnnHandle_t: These are thread-safe APIs that don't enqueue any CUDA work on a stream. They can be called directly without any extra precautions.
B) APIs that take a cudnnHandle_t and perform CUDA work. The CUDA context needs to be acquired and the stream needs to be set beforehand, calls need to be serialized. A CudnnHandle instance guarantees that this work has been performed before calling cuDNN.
C) APIs that do take a cudnnHandle_t, but (presumably, the API makes no guarantees) still don't perform any CUDA work. This is limited to the API to setup RNN descriptors. Calls need to be serialized, but most likely we wouldn't need to acquire the CUDA context or set the stream. We still do though using the legacy default stream, because there are no guarantees.

Add logic for StridedSlice ops in ShapeRefiner::ConstantPartialShape().
This mimics the logic in tensor_util.constant_value_as_shape, allowing
the C++ shape inference code to infer more shapes than it could before.
This change also adds an optional stride argument to InferenceContext::Subshape().

ShapeRefiner fix: some variant-type tensors have handle data.
ShapeRefiner::AddNode() would only propagate handle data for
DT_RESOURCE tensors, but not DT_VARIANT. The Python shape inference
logic in common_shapes.py handled this correct, which is why we didn't
notice this earlier. In particular, list ops use DT_VARIANT with
handle data.

Refactor TensorArray to avoid copies and memory allocations when executing eagerly.
With this change, writes to TensorArrays when eager execution is enabled take O(1) time instead of O(n). Additionally, whereas writing to a TensorArray when constructing a graph results in allocating a new Python TensorArray object, writing to a TensorArray with eager enabled no longer performs that allocation (graph construction uses these allocations to ensure correctness of control flow and gradients, but this isn't necessary when executing eagerly). Finally, this change also removes the artificial write-once semantics of TensorArrays when executing eagerly.

[Remote functions] Only set the default runner *after* resolving the remote FLR.
Previously, if the `runner` was not specified for a function
execution, we would immediately set it to the default runner of the
*local* FLR, even if the function was to be executed remotely. This
change postpones the resolution of the default runner until after the
function invocation has been routed to the FLR that will actually
execute it.
As a result, we avoid the pathological case where a GPU device using a
private threadpool (TF_GPU_THREAD_MODE=gpu_private) ends up running
all of the ops for the CPU-side input pipeline on the private
threadpool.
