Object: Fix COFF import file's symbols.

If a symbol is marked as "data", the symbol should be exported

Re-apply r246276 - Object: Teach llvm-ar to create symbol table for COFF short import files
...
This patch includes a fix for a llvm-readobj test. With this patch,
the tool does no longer print out COFF headers for the short import
file, but that's probably desirable because the header for the short
import file is dummy.

Object: Teach llvm-ar to create symbol table for COFF short import files.
...
COFF short import files are special kind of files that contains only
DLL-exported symbol names. That's different from object files because
it has no data except symbol names.
This change implements a SymbolicFile interface for the short import
files so that symbol names can be accessed through that interface.
llvm-ar is now able to read the file and create symbol table entries
for short import files.

lld might end up using a small part of this, but it will be in a much
refactored form. For now this unblocks avoiding the full section scan in the
ELFFile constructor.
This also has a (very small) error handling improvement.

Add support for reading members out of thin archives.
...
For now the Archive owns the buffers of the thin archive members.
This makes for a simple API, but all the buffers are destructed
only when the archive is destructed. This should be fine since we
close the files after mmap so we should not hit an open file
limit.
