Summary:
This change adds support for the GNU --target flag, which sets both --input-target and --output-target.
GNU objcopy doesn't do any checking for whether both --target and --{input,output}-target are used, and so it allows both, e.g. "--target A --output-target B" is equivalent to "--input-target A --output-target B" since the later command line flag would override earlier ones. This may be error prone, so I chose to implement it as an error if both are used. I'm not sure if anyone is actually using both.

In this diff we move out CopyConfig from llvm-oobjcopy.cpp into a separate header CopyConfig.h
to enable us (in the future) reuse this class in the other implementations of objcopy (for coff, mach-o).
Additionally this enables us to unload the complexity from llvm-objcopy.cpp a little bit.
Test plan: make check-all
