[ELF] Reject certain unknown section types (#85173) Unknown section sections may require special linking rules, and rejecting such sections for older linkers may be desired. For example, if we introduce a new section type to replace a control structure (e.g. relocations), it would be nice for older linkers to reject the new section type. GNU ld allows certain unknown section types: * [SHT_LOUSER,SHT_HIUSER] and non-SHF_ALLOC * [SHT_LOOS,SHT_HIOS] and non-SHF_OS_NONCONFORMING but reports errors and stops linking for others (unless --no-warn-mismatch is specified). Port its behavior. For convenience, we additionally allow all [SHT_LOPROC,SHT_HIPROC] types so that we don't have to hard code all known types for each processor.
