This removes `m_forward_decl_die_to_compiler_type` which is a map from `const DWARFDebugInfoEntry *` to `lldb::opaque_compiler_type_t`. This map is currently used in `DWARFASTParserClang::ParseEnum` and `DWARFASTParserClang::ParseStructureLikeDIE` to avoid creating duplicate CompilerType for the specific DIE. But before entering these two functions in `DWARFASTParserClang::ParseTypeFromDWARF`, we already checked with `SymbolFileDWARF::GetDIEToType()` if we have a Type created from this DIE to avoid trying to parse the same DIE twice. So, this map is unnecessary and not useful.
