[llvm-objcopy] --[de]compress-debug-sections: don't compress SHF_ALLOC sections, only decompress .debug sections
Simplify --[de]compress-debug-sections to make it easier to add custom section [de]compression.
Change the following two behaviors to match GNU objcopy.
* --compress-debug-sections compresses SHF_ALLOC sections while GNU
doesn't.
* --decompress-debug-sections decompresses non-debug sections while GNU
doesn't.

[llvm-objcopy] --compress-debug-sections: remove tail padding for ELFCLASS32

[llvm-objcopy] --compress-debug-sections: remove tail padding for ELFCLASS32
For an ELFCLASS32 object, a compressed section due to --compress-debug-sections={zlib,zstd} has a
tail padding of 12 zero bytes. zlib happily allows this while zstd is rigid and
reports `error: '{{.*}}': failed to decompress section '.debug_foo': Src size is incorrect`.
Cole Kissane reported the problem.
