[Object] Extract format-agnostic BBAddrMap decoder

This is part of patches to port BBAddrMap to COFF.

Move format-agnostic BBAddrMap decode logic out of ELF.cpp into
BBAddrMap.cpp, and expose a shared decodeBBAddrMapPayload helper in
BBAddrMap.h.

Keep ELF-specific steps (section decompression and relocation
translation) in ELF.cpp, and delegate payload decoding to the
shared helper.

Error messages in the decoder are updated to use the generic
"BB address map" instead of the ELF-specific "SHT_LLVM_BB_ADDR_MAP"
since the decoder is now shared across object formats.

This refactor prepares follow-up work to let COFF and ELF share
the same BBAddrMap decoding logic.
