[SYCL][E2E] Add InlineAsm/lit.local.cfg to clean up REQUIRES/UNSUPPORTED

[ayylol]

All test in this folder use REQUIRES: gpu,linux and UNSUPPORTED: cuda, hip. So using a lit.local.cfg file makes sense here.

what is sg-16 ?

[cperkinsintel]

also, will this be impacted by #16314 ?

Subgroup size 16, the test uses sycl::reqd_sub_group_size(16)

also, will this be impacted by #16314 ?

Nikita did mention that here #16314 (comment)

Hi @cperkinsintel! Could you please take one more look?

[ayylol]

@cperkinsintel / @intel/llvm-reviewers-runtime Could you have another look at this.

IMO, that should be REQURIES: <intel-gpu>, although I don't know if that's possible. Also, it might be a good idea to have an extra directory for that (InlineAsm/IntelGPU).

@aelovikov-intel There were just two tests that didnt have UNSUPPORTED: hip (asm_8_empty.cpp, and asm_16_empty.cpp). Would you happen to know why these two are exceptions, I see you were the one that last changed these lines?

Because "empty" inline asm can be compiled there? I still think we should be creating a dedicated InlineAsm/IntelGPU folder and moving all but these two tests there.

@aelovikov-intel I checked locally, the tests that were not marked as unsupported for hip are actually still unsupported and fail to build for hip because of the subgroup size requirements. This means every test in this folder was unsupported for cuda/hip, so instead of making the IntelGPU subfolder i just added REQUIRES: target-spir to the lit.local.cfg file

I can live with that.
