[SYCL][LIT] UNSUPPORTED sycl/test/abi/sycl_symbols_windows.dump on Windows

Windows ABI test broke after #20821

[uditagarwal97]

Looks like different ABI symbols are being generated for Windows pre and post commit.
Unlike pre-commit, for post-commit, the following symbols are absent:

??0device@_V1@sycl@@QEAA@$$QEAV012@@Z
??0device@_V1@sycl@@QEAA@AEBV012@@Z

One difference is that pre-commit uses MSVC's cl while post-commit uses icx - I wonder if different compilers are generating different ABI symbols.

That sounds somewhat likely, but maybe we can trick the latter to think that the symbols are exported.

Can we commit a test fix and follow-it up with a better fix if needed or revert the original commit? Thanks

I'm trying to come up with a proper fix. In the meanwhile, I'd be fine disabling this test - we are anyway in the ABI break window

Fine with me, thx!
