问题#183
在 2in1（PC）、平板开启自由多窗、平板电脑模式下，应用窗口状态恒为 FLOATING，被当成手机/平板的「系统小窗」处理：窗口内进入横屏全屏时套用了横屏小窗的 0.75 缩放与
enableLandscapeMultiWindow，每次进出全屏界面整体缩放一次，观感即 DPI 突变。修复
Window.isInFreeWindowMode()（API 22，与 compatibleSdkVersion 一致）判断窗口是否处于系统自由窗口模式，随getWindowState下发初值，并监听freeWindowModeChange，运行中开关自由多窗/切换电脑模式时实时推送给 Dart。_miniWindow && _landscape && !_freeWindowMode；模式变化时重新评估缩放（抽出_applyMiniWindowLandscape()复用）。deviceType判断：平板（含带电脑模式的 MatePad Edge，实测上报tablet）都不是2in1，且自由多窗可在运行中开关。
