fix(gpu): fix GPU VRAM size parsing failure on multi-line gpu-info

[add-uos]

Split gpu-info by single "\n" and parse each line separately instead of splitting the whole content by "\n\n" and ":" on the entire string.

修复多行gpu-info文件显存大小解析失败的问题，改为逐行分割解析。

Log: 修复显存大小解析失败问题
PMS: BUG-372403
Influence: 修复后含多行的gpu-info文件能正确解析显存大小并显示。

Summary by Sourcery

Fix GPU VRAM size parsing from multi-line gpu-info files by parsing each line separately.

Bug Fixes:

• Correct gpu-info parsing logic so VRAM size is properly extracted when the file contains multiple lines.

Enhancements:

• Update SPDX copyright header years for DeviceGpu.cpp.

File-Level Changes

Change	Details	Files
Fix GPU VRAM size parsing by switching from whole-file splitting to per-line parsing of gpu-info content.	Change gpu-info content splitting from double-newline ('\n\n') to single-newline ('\n') so each line is processed independently. For each non-empty line, split that line on ':' with QT_SKIP_EMPTY_PARTS to extract key/value pairs, instead of splitting the entire file content. Retain the skip logic for empty or incorrectly formatted lines to avoid invalid entries in the parsed result.	deepin-devicemanager/src/DeviceManager/DeviceGpu.cpp
Update SPDX copyright header year range.	Extend the SPDX-FileCopyrightText year range from '2022' to '2022 - 2026' in the DeviceGpu source file.	deepin-devicemanager/src/DeviceManager/DeviceGpu.cpp

★ 总体评分：95分

■ 【总体评价】

代码修复了GPU信息解析中变量误用导致的逻辑错误，提升了解析的准确性
逻辑修复完全正确且无安全漏洞，仅因修改范围较小未达满分

■ 【详细分析】

• 1.语法逻辑（完全正确）✓

在 DeviceGpu::setHwinfoInfo 函数中，原代码在 foreach 循环内错误地对外层变量 allStr 进行 split 操作，导致无法正确解析单行键值对。修复后改为对当前遍历的 item 进行 split(":")，同时将行分隔符从 \n\n 调整为 \n，逻辑完全符合预期。
潜在问题：无
建议：无

• 2.代码质量（良好）✓

修复了明显的变量引用错误，代码逻辑更加清晰。保留了原有的空行跳过和长度校验逻辑，符合编码规范。
潜在问题：无
建议：无

• 3.代码性能（无性能问题）✓

修复前在循环内反复对整个文件内容字符串 allStr 进行切分，存在不必要的性能损耗。修复后仅对当前 item 进行切分，消除了冗余计算，性能表现良好。
潜在问题：无
建议：无

• 4.代码安全（存在0个安全漏洞）✓

漏洞对比统计：新增漏洞 0 个，减少漏洞 0 个，持平 0 个
本次修改仅涉及字符串解析逻辑的修正，未引入任何外部输入处理、文件操作或网络通信的安全风险，不存在攻击面。

• 建议：无

■ 【改进建议代码示例】

// 当前代码已修复核心问题，无需进一步修改。以下为完整上下文展示：
if (file.open(QIODevice::ReadOnly)) {
    qCDebug(appLog) << "gpu-info file opened successfully.";
    QString allStr(file.readAll());
    QStringList items = allStr.split("\n");
    file.close();
    foreach (const QString &item, items) {
        if (item.isEmpty()) {
            continue;
        }
        QStringList tmpItems = item.split(":", QT_SKIP_EMPTY_PARTS);
        if (tmpItems.size() != 2) {
            continue;
        }
        // 后续处理逻辑...
    }
}
