  [llvm-nm][GOFF] Display archive attributes in GOFF archives through --print-armap

GOFF archive symbol table entries contain an attribute word in addition
to the archive member offset. The low three bits describe whether the symbol is
64-bit, uses XPLink, or belongs to the WSA namespace (which was briefly mentioned
in e2c8fa09872cfacba7f73599dcf8557971ebe865).

This patch extends `llvm-nm --print-armap` to print the attribute value (in hex) and
its decoded description beside a symbol and its corresponding member when processing
a GOFF archive. This will functionality will be used to help validate full support for writing
GOFF archives in a subsequent llvm-ar patch.

The output for non-z/OS archives is unchanged.
