[NFC][SYCL][E2E] Split long tests

[bratpiorka]

This PR splits a long‑running test that could time out on slower machines (e.g. new system used for testing CUDA 13):

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

This PR splits several long-running SYCL E2E tests into smaller, more focused binaries to reduce timeout risk on slower test machines.

Changes:

• Split Vulkan/SYCL bindless image interop read/write tests into channel/sample/semaphore-focused test entrypoints.
• Split sampled image read tests into separate 1D and 2D entrypoints, moving shared logic into a common implementation.
• Split WorkGroupMemory “basic usage” coverage into separate pointer vs non-pointer entrypoints, moving shared logic into a common implementation.
