#4763: QScript is broken on 64-bit Windows

-------------------------------+-------------------------------------
Building a 64-bit Windows build succeeds, but running it (for example,
starting a skirmish game) throws a bunch of script errors.
What appears to be happening is something similar to this Qt bug (which is
still unresolved) that apparently only affects 64-bit Windows builds of
Qt: https://bugreports.qt.io/browse/QTBUG-39416
- When `checkResearch` in `mp\multiplay\skirmish\nb_includes\research.js`
is triggered,
- `enumIdleStructList` in `mp\multiplay\skirmish\nb_includes\stats.js` is
called
- This seems to properly enumerate the research labs...
- But at some later point what gets passed to `js_structureIdle` is a
`QScriptContext` that is:
{{{
filter(function () {
[native code]
}) at -1
}}}
Whereas on macOS, what gets passed to `js_structureIdle` is a
`QScriptContext` that is:
{{{
<native>([object Object], 0, [object Object],[object Object]) at -1
}}}
Hence, on 64-bit macOS (and 32-bit Windows), `context->argument(0)` is a
'''structure Object''',
but on 64-bit Windows it's `function () { [native code] }`.
At this point, I think it's unlikely that any QScript bugs on 64-bit
Windows will *ever* be resolved (given QScript's deprecated status).
So 64-bit Windows builds appear to be broken until we can switch to a
different JavaScript engine.
