Currently, only custom sections can be selected by operations that use section names, because only custom sections have explicit names (whereas known sections have names defined by the spec and only use their indices in the binary format). This CL makes objdopy use the spec-defined names for these sections, allowing them to be used in operations such as dumping and removal. This is a prerequisite for fixing https://github.com/emscripten-core/emscripten/issues/13084 Differential Revision: https://reviews.llvm.org/D126509
