SWDEV-283266 - Workaround RTC macro in vector types
SWDEV-283266 - Workaround RTC macro in vector types

Temporarily disable __HIPCC_RTC__ in hip_vector_types.h
while the upstream clang headers are outdated on mainline.
Once upstream patch has landed in mainline, revert this
change. This is a workaround for hiprtc testing.
