Subject: Ability to switch language under platform eglfs/linuxfb

I need to change keymap under platforms eglfs and linuxfb (without wayland).
I use the function QEglFSFunctions::loadKeymap(const QString&), but there's
no way to switch between english and another language than to press AltGr as
a modifier. I added the function that allows to change the language. And also
added the ability to switch the keymap and language for the platform linuxfb

and also added the ability to switch the keymap and language for the platform linuxfb

Task-number: QTBUG-72452

+    \class QLinuxFbFunctions
+    \inmodule QtPlatformHeaders
+
+    \brief The QLinuxFbFunctions class is an inline class containing
+    platform-specific functionality for the linuxfb platform plugin that is
+    typically used on systems running Embedded Linux or Android.
+
+    \note There is no binary compatibility guarantee for this class,
+    meaning that an application using it is only guaranteed to work with the Qt
+    version it was developed against.

+
+/*!
+    \typedef QLinuxFbFunctions::LoadKeymapType
+
+    Function type for loadKeymap.
+*/
+
+/*!
+    \fn QByteArray QLinuxFbFunctions::loadKeymapTypeIdentifier()
+
+    \return the identifier that can be passed to
+    QGuiApplication::platformFunction() to query the entry point for the
+    loadKeymap function implementation.
+*/
+
+/*!
+    \fn void QLinuxFbFunctions::loadKeymap(const QString &filename)
+
+    Loads and switches to the keymap from \a filename. When \a filename is
+    empty, the default keymap, which is either the built-on one or the keymap
+    given in the plugin specification, is restored.
+
+    \note This is functional only when the evdev keyboard support code is
+    compiled in to the platform plugin. When using external generic plugins via
+    the \c{-plugin} argument, or when the environment variable
+    \c{QT_QPA_FB_DISABLE_INPUT} is set or when building Qt without evdev
+    support, this function will have no effect.
+*/
+
+/*!
+    \fn void QLinuxFbFunctions::switchLang()
+
+    Switches between English and other language when the keymap is loaded.
+    Usually the keymap contains two languages: English and national. When
+    you load the keymap, English is selected by default. This function allows
+    to switch between these languages.
+
+    \note This is functional only when the evdev keyboard support code is
