Avoid double caching glyphs in raster/QPA/FreeType

Since FreeType has internal caching, it has had a special
code path in the raster engine which avoided using Qt's glyph
cache, as that would be redundant. However, when compiling
with QPA, we want the same behavior without being able to
access the QFontEngineFT class. To achieve this, I've made
a new abstraction and added it to QFontEngine which allows
the FT engine to provide direct pointers into the alpha maps
stored by FT. This requires a locking/unlocking mechanism.

Yes, the QFontEngine::alphaMap* API is slowly becoming a horrible
mess, but due to time constraints, the task of refactoring these
functions into a more flexible API needs to wait. I've added a

Stop the mis-use of navigate to find the parent.

   void std::vector<T>::push_back(T &&);

so attempting to get the address for push_back is ambiguous.

Instead of hardcoding the function signature, the better and more

resolution itself, also allowing for implicit conversions to take place.

Add benchmark for QChar

The benchmark isn't exhaustive, but tests the functions
that are heavily used by QtDeclarative.

For performance reasons, QtDeclarative has its own
implementation of various QChar functions (in
qdeclarativeutils_p.h). But we want to make the actual
QChar functions as fast, so that QtDeclarative can also
use them.
