wayland: Send synthesized release to press surface

When a drag starts, wl_pointer.leave clears the pointer focus and
button state. At the end of the drag, releaseButtons() sends a
synthesized release without a target surface. The event can therefore
reach a different window, while the item that handled the press does
not receive the release and keeps its drag state active.

Remember the surface that receives the first button press after mouse
grab routing, and use it as the target of the synthesized release.
Clear the saved surface after the final regular button release.
QPointer ensures that the fallback remains safe if the surface has
already been destroyed.

ohos: rename QtOhosAppKit module to QtHarmonyExtras

The module's external identity had two problems. "Ohos" is the
toolchain name, but Qt's user-facing name for this OS is now Harmony
(Q_OS_HARMONY, QOperatingSystemVersion::HarmonyOS). And "AppKit" is
Apple's macOS framework, entirely unrelated to OpenHarmony - Qt
component names should not overlap with unrelated parts of Qt, let
alone with unrelated non-Qt components.

Name the module QtHarmonyExtras, following the QtXxxExtras convention
for platform-specific add-on APIs.

Rename the external identity:

 - module OhosAppKit => HarmonyExtras
 - namespace QtOhosAppKit => QtHarmonyExtras
 - Q_OHOSAPPKIT_EXPORT => Q_HARMONYEXTRAS_EXPORT
 - QT_BUILD_OHOSAPPKIT_LIB => QT_BUILD_HARMONYEXTRAS_LIB
 - include path QtOhosAppKit/ => QtHarmonyExtras/
 - qtohosappkitglobal_p.h => qtharmonyextrasglobal_p.h
 - directory ohos/ohosappkit/ => ohos/extras/

Internal names stay on the "Ohos" prefix (qohos* file names, QOhos*
implementation classes, QtOhos plugin namespace), matching the corelib
convention.

QAuthenticator: change method selection to prefer strongest method

The method selection loop in parseHttpResponse() uses raw enum
comparisons (method < X) to decide whether to upgrade to a stronger
method. The enum is ordered, which gives DigestMd5 the highest numeric
value. As a result, Digest-MD5 is preferred over both NTLM and
Negotiate (Kerberos) when a server offers multiple methods.

Change the ordering to prefer the strongest available method.
