When storing complex types in the list and inserting in the middle,
we ended up in some cases moving the items in the list onto itself,
to make space for 0 new items.
Obviously that's not a very good idea. It was not a huge deal for
POD or relocatable types as we'd use memmove in that case which would
return quickly. But for complex types, we actually did copy around
half of the items stored in the list onto themselves.

Introduce emplaceBack implementation as append is quite a special case

While at it, change append(t) to use emplaceBack(t)
For workloads like:

It looks like we can drastically simplify the way QADP grows without
sacrificing much:
1. append-only use cases should have the same performance as before
2. prepend-only use cases should (with the help of other commits) get
additional performance speedup
3. mid-insertion is harder to reason about, but it is either unchanged
or benefits a bit as there's some free space at both ends now
4. mixed prepend/append cases are weird and would keep excess free
space around but this is less critical and overall less used AFAIK
Now, QList would actually start to feel like a double-ended container
instead of "it's QVector but with faster prepend". This commit should
help close the performance gap between 6.0 and 5.15 as well
As a drawback, we will most likely have more space allocated in mixed
and mid-insert cases. This needs to be checked

Prepend in QList was using insert() logic that always uses append-aware
functions. This results in the fact that freeSpaceAtBegin() is always 0
and forces us to actually allocate on *every* call (with the same
capacity!). Vicious cycle is hot-fixable with introduction of
emplaceFront (or anything prepend-aware, really)
This brings me from 632ms to 0.65ms for 100k iterations of
list.prepend(int(0)). Still ~3x worse than QList in 5.15 but much
faster than QVector, which takes 382ms in the same workload
Not addressed:
- QString/QBA
- Other prepend functions in QList e.g. prepend(it1, it2)
- Lower-level array operations that should just be extended

emscripten_async_run_in_main_runtime_thread_ schedules
an async call on the on the main thread. However, the
calls are ordered, also in respect to _synchronous_ calls
to the main thread (for example those made during file
write/flush).
Making a synchronous call from a secondary thread may
then cause Emscripten to service previously scheduled
async calls during the synchronous call. This can cause
a deadlock if:
- a secondary thread makes a sync call while holding a lock, and
- a previously scheduled async call attempt to acquire the same
lock on the main thread.
(See https://github.com/emscripten-core/emscripten/issues/10155
for sample code)
Avoid this case by adding a second zero-timer async call;
this way Qt should process events when the main thread
becomes idle.

In 4e400369c0 we deprecated
normalizedPos() because we suspect it's a legacy feature that few
users will need. However Qt developers keep bringing up the continued
usage in autotests over and over. (It's IMO not wrong to keep testing
deprecated functions in autotests, but the warning keeps attracting
attention.)
Of course it will turn out that normalizedPos() has users; we just
don't know how many. One way to look at it is: why should they copy
a snippet of code to calculate it, when it costs us so little to
continue to provide this accessor.
It might also turn out that some users will complain that in Qt 5
it was passed through from the device driver (or at least from the
window system API) to the application, and perhaps the replacement will
not always work, for example if availableVirtualGeometry() ends up
wrong, or there is some strange scenario that generates events that are
out-of-bounds for the device that the event professes to come from, so
that the "normalized" coordinates also go outside the [0..1] range.
We reserve the right to put back the storage in QEventPointPrivate if
the need arises; so that's why this function is not inline.
We continue to hope that startNormalizedPos() and lastNormalizedPos()
are used even less and won't be missed much, because it would be
wasteful to store them all the time if only a few users need them.
