LOG: [AMDGPU][MC] Fix disassembler for VIMAGE when non-first vaddr is v0 (#113569)

For disassembler tables we use *V1_V4* variants for VIMAGE and then
remove unused vaddr fields. *V1_V1* variant, which has every vaddr
field other than vaddr0 set to 0, was also enabled and caused confusion
when decoding cases which used v0 (whose encoded value is 0)

Added:
