Implements urCommandBufferAppendKernelLaunchExp function to append kernel to a command buffer.
Implements urCommandBufferAppendKernelLaunchExp function to enqueue a command buffer to a cuda stream.
Enable all tests supported by the current state of the Cuda backend.

Sets a ScopedContext before enqueuing command buffer.

* [SYCL][Graph] Adds missing exception catch

Implements CUDA backend support for:
- memcpyUSM
- memcpy Device to Device (1D and 2D)
- memcpy Host to Device (Write 1D and 2D)
- memcpy Device to Host (Read 1D and 2D)
Enables all remaining e2e tests

* [SYCL][Graph] Implement graph creation and finalization for CUDA backend

Implements CommandBuffer creation, retain, release and finalize functions
for the cuda backend.
These functions rely on the cuda graph feature which is part of cuda runtime.
Consequently, this PR adds the required linking dependencies.
Fixes a commandbuffer bug in the cuda pluging initialization.
Reports cuda backend as supported for the graph extension.
Adds a tests that creates and finalizes an empty graph.

…ecessary e2e test

The offsets are taken into account after CUdeviceptr type casting.

This patch does not fix e2e test failure on AWS.

This reverts commit cdc19b1.

- Commands which enqueue to a command graph now correctly respect their dependencies by waiting on them.
- Prevents issues where allocation commands with dependent copies could be delayed due to device being busy and execute in an incorrect order with regards to future command graph executions.
