LOG: [SPARC] Make SPARC_REGISTER Sparc specific in llvm-readobj and LLDB (#206316)

The commit 4418a8e5 failed to limit SPARC_REGISTER to Sparc targets
only, which causes conflict when adding new dynamic tags for other
targets.

Added: 
    

Modified: 
    lldb/source/Plugins/ObjectFile/ELF/ObjectFileELF.cpp
    llvm/include/llvm/BinaryFormat/DynamicTags.def
    llvm/lib/Object/ELF.cpp

Removed:
