...so we can use FileDescriptorStore with fds that don't refer to regular files. Right now ChildProcessLauncherFileData's files_to_preload is the only way to pass a file via FileDescriptorStore without editing child_process_launcher internals, so make it hold a variant<FilePath, int> instead of just a FilePath. NOTE: At this point on Linux there are 3 ways to "name" file descriptors passed to a child process: 1. Normal file descriptor table 2. base::GlobalDescriptors (integer keys map to fd numbers) 3. base::FileDescriptorStore (string keys map to base::GlobalDescriptors keys). #1 can be modified with ChildProcessLauncherFileData::additional_remapped_fds, #2 can be modified with ContentBrowserClient::GetAdditionalMappedFilesForChildProcess(), and #3 can be modified with ChildProcessLauncherFileData::files_to_preload.
