45ae553109 [llvm-objcopy] Remove support for legacy .zdebug sections
clang 14 removed -gz=zlib-gnu support and ld.lld removed linker input support
for zlib-gnu in D126793. Now let's remove zlib-gnu from llvm-objcopy.

* .zdebug* sections are no longer recognized as debug sections. --strip* don't remove them.
  They are copied like other opaque sections
* --decompress-debug-sections does not uncompress .zdebug* sections
* --compress-debug-sections=zlib-gnu is not supported

It is very rare but in case a user has object files using .zdebug . They can use
llvm-objcopy<15 or GNU objcopy for uncompression.
--compress-debug-sections=zlib-gnu is unlikely ever used by anyone, so I do not
add a custom diagnostic.

ad29d29130 [llvm-objcopy][NFC] More error cleanup
Summary:
This removes calls to `error()`/`reportError()` in the main driver (llvm-objcopy.cpp) as well as the associated argv-parsing (CopyConfig.cpp). `logAllUnhandledErrors()` is now the main way to print errors.

There are still a few uses from within the per-arch drivers, so we can't delete them yet... but almost!

6e4dc6f23f [llvm-objcopy] Move elf-specific tests into subfolder
In this diff the elf-specific tests are moved into the subfolder llvm-objcopy/ELF
(the change was discussed in the comments on https://reviews.llvm.org/D54674).
A separate code reivew wasn't sent for this change 
since Phabricator is failing to create such a large diff.

Test plan: 
make check-all
make check-llvm-tools
make check-llvm-tools-llvm-objcopy
