Update slang-rhi and fix error handling (#5485)

Update slang-rhi to pick up a fix in webgpu compilation error handling.

In doRenderComparisonTestRun(), only return TestResult::Pass if the
shader is ran actually compiled.

A similar check is in place elsewhere in slang-test-main, but was
missed in doRenderComparisonTestRun().

Add two tests to the github CI skiplist, and use the skiplist in one
additional CI config that was running without it.

Closes 5291
