[HIP] fix bundle ID for amdgcnspirv (#139112)
Currently ROCm 6.4.0 only recognize spirv64-amd-amdhsa- in bundle ID.
spirv64-amd-amdhsa-unknown causes all HIP apps compiled for amdgcnspirv
to fail.
Previously we fixed a similar issue for
amdgcn-amd-amdhsa-unknown. This patch extends that to
spirv64-amd-amdhsa-unknown.
