Android: Fix QMenu on 64 bit

The platform menu tags in Qt are actually the pointers, so they are
64-bit values when the build is 64 bit. Since menu IDs in Android
are 32-bit ints, we cannot cast back and forth like we do. To fix
this, we add a separate hash of menu IDs to allow mapping between
Java and C++. For easier book-keeping, we add the hashes to the
menu bar and menu classes, so that we can easily recycle old menu
IDs when they are no longer in use.

Note that overriding the tag on the menus by calling setTag() will
not work, since Qt Widgets will later override it again by setting
it back to the menu's pointer.

[ChangeLog][Android] Fixed an issue where menus would not work on
64 bit builds.
