debug/elf: add version information to all dynamic symbols Currently, File.ImportedSymbols is the only API that exposes the GNU symbol version information for dynamic symbols. Unfortunately, it also filters to specific types of symbols, and only returns symbol names. The cgo tool is going to need symbol version information for more symbols. In order to support this and make the API more orthogonal, this CL adds version information to the Symbol type and updates File.DynamicSymbols to fill this in. This has the downside of increasing the size of Symbol, but seems to be the most natural API for exposing this. I also explored 1) adding a method to get the version information for the i'th dynamic symbol, but we don't use symbol indexes anywhere else in the API, and it's not clear if this index would be 0-based or 1-based, and 2) adding a DynamicSymbolVersions method that returns a slice of version information that parallels the DynamicSymbols slice, but that's less efficient to implement and harder to use. For #31912.
