[DXIL][test] Fix a few tests now that HLSL functions are internalized (#106437)

These tests have been failing since db279c7 "[HLSL] Change default
linkage of HLSL functions to internal (#95331)". This presumably went
unnoticed because they're not run by default since they rely on an
external tool (dxil-dis).
