[elfabi] Add support for reading DT_SONAME from binarieslinaro-local/ci/tcwg_kernel/llvm-master-aarch64-next-allnoconfig
This change gives the llvm-elfabi tool the ability to read DT_SONAME from a binary ELF file into an ELFStub.
Added:
- DynamicEntries struct for storing dynamic entries that are relevant to elfabi.
- terminatedSubstr() retrieves a null-terminated substring from a StringRef.
- appendToError() appends a string to an error, allowing more specific error messages.
