Add a way to set the default render type of text-like elements

f3446071da8357620d0c8593a04e3b4fbba88f21 introduced a build-time
way to select the default render type of text-like elements.
This patch adds also a way to select it at runtime, via a setter
on QQuickWindow. (QQuickWindow has been chosen as convenience,
rather than adding another namespace/class to just have this
setter.)

Given that QT_QUICK_DEFAULT_TEXT_RENDER_TYPE was never documented,
I've taken the liberty of changing the accepted values for it
(to match the new enumerator names in QQuickWindow, rather than
the ones in QQuickText/QQuickTextEdit/etc.).

[ChangeLog][QtQuick][QQuickWindow] It is now possible to set the
default render type of text-like elements globally via the
QQuickWindow::setTextRenderType() function. If you were using
the (undocumented) QT_QUICK_DEFAULT_TEXT_RENDER_TYPE macro
when building Qt Quick for the same purpose, note that the
macro value needs now to be set to the "NativeTextRendering"
value, instead of "NativeRendering".
