ohos: Clean up the application state tracker

Drop the unused FocusWindowEvent type alias.

Store the received application state directly rather than through a
redundant local variable.

ohos: Derive application state from the OHOS lifecycle

ApplicationStateTracker derived Qt::ApplicationActive/Inactive from
window focus, reporting the application inactive whenever no window held
focus. A popup is created non-focusable on OHOS, so when such a popup is
the application's only visible window -- a top-level popup with no
parent, such as a parentless QMenu -- the tracker reported
Qt::ApplicationInactive; QtWidgets reacts to that by calling
closeAllPopups() and dismisses the popup before it is shown.

Derive the active/inactive distinction from the OHOS ability lifecycle
(foreground/background) that the platform already reports, and use
window visibility only to refine it to Qt::ApplicationHidden. A
foreground application is active whether or not one of its windows holds
focus, which removes the need to track window focus or to special-case
popups.

ohos: Compare platform-reported window states, not the requested one

QOhosPlatformWindow::m_windowState is updated both at window creation
and from setWindowState(), so it reflects the requested state. Comparing
an incoming platform state change against it drops updates whose
requested and applied values coincide, so e.g. a maximize is never
reported to Qt.

Compare the previously received platform state instead, tracked
separately in m_lastWindowState (a std::optional left empty until the
first report, so that report is always delivered).

Filter duplicate FULL_SCREEN status notifications in
handleWindowStatusChange(), observed on real devices. MainWindow views
in non-PC mode are exempt: initialize() pre-seeds their status to
FULL_SCREEN, so their first real notification is still processed.

ohos: Fix checkPermission() never reporting Denied

On OHOS, QCoreApplication::checkPermission() never reports Denied:
after the user explicitly denies a permission it still returns
Undetermined, whereas Android and iOS report the real decision. So
portable code that branches on Denied - e.g. to stop prompting and open
settings - misbehaves on OHOS: it never sees Denied and keeps
re-prompting.

The lossy result comes from querying the binary checkAccessToken, which
cannot tell a denied permission from one never requested.

Since API 20 OHOS also offers the AtManager.getSelfPermissionStatus()
JS API, which returns a full status: GRANTED, DENIED, NOT_DETERMINED,
INVALID or RESTRICTED.

Have checkPermission() query AtManager.getSelfPermissionStatus() so it
reports the real status. Where a QPermission maps to several OHOS
permissions, it is granted only if all are granted, denied if any is
denied, and undetermined otherwise. requestPermission() already behaved
correctly and is unchanged.

ohos: kill QOhosOptional alias use in clipboard/UDMF files

The QOhosOptional<T> alias for std::optional<T>, together with its
makeQOhosOptional() and makeEmptyQOhosOptional() helpers, is being
eliminated in favor of using std::optional directly.

Replace every remaining use in the clipboard and data-transfer (UDMF)
files with plain std::optional and add <optional> includes where the
type is used and the paired header does not already provide one.

Where std::optional is the target type (a function return or an
assignment), use the underlying value directly instead of wrapping it,
and return {} instead of std::nullopt; keep the explicit optional only
where it is required, e.g. in conditional expressions and in lambdas
with a deduced return type.

Drop the now-unused qohosplugincore.h include from the files where
QOhosOptional was the only symbol taken from it.
