The Windows and Cocoa font engines ignored the stretch factor when
the pixel size is so large that QPainterPath rendering is used
instead of native.

This was added as a platform-specific implementation of the multi engine
in 2005, before this code was generalized, and it currently only has the purpose
of special handling loadEngine().
The way this was special handled was by creating a new QFontEngine for every
fallback family *every* time, never checking if the font engine already exists
in the cache (like the superclass implementation does). The result of this was
that if you had 500 fonts and each of them had 500 fallback fonts, and made
a loop that would load all of them, then you would get 250000 font engines.
At some point before this, we would run out of available handles and crash.
There shouldn't be any need to have special handling of fallback font loading
on Windows (i.e. all the platform specific parts should go through the normal
mechanisms in QPA), so lets just go through the superclass implementation instead.
[ChangeLog][Windows][Text] Reduced the number of font engines that are
created when loading new fonts, fixing crashes in some special cases where
a large number of fonts are created during a short period of time.

Replace by reinterpret_cast or const_cast, respectively.
Use auto when initializing a variable to fix Clang warnings
about repeating the type name, do minor tidying along the way,
and a few conversions of 0 or NULL to nullptr.

In order to support the generated EUDC.TTE font for
End-User Defined Characters on Windows, we need to allow
fallback fonts which are not part of the default font
collection. This is the same as change
21c7421d4e86b6048f9c2c7a9a81ec4ff1ed278c, but adapted to
the fallback font code path.
Without this change, the EUDC file would still be loaded,
but it would be loaded through the GDI fallback, and we
would display an error message on the console.

This reverts 2bc619c30ef08c9b5e2aaa3370d184670acd73ad, which tried to
fix an unspecified problem by regarding all fonts with EBDT tables as
potential bitmap fonts. The change log does not have any reference to
a bug report or a problematic font. It also singled out Windows and GDI
as the only font engine where this was necessary, which caused difference
in behavior between different platforms, and even a difference in
behavior on Windows when setting the hinting preference or turning on
high-DPI scaling.
The fact is that any font may have an EBDT table, and Microsoft has this
for the smaller pixel sizes of many of their default fonts, e.g. Calibri.
The result was that Qt would detect these as bitmap fonts and refuse to
use distance field rendering for them.
If there are fonts where it is a real problem that some glyphs only exist
as bitmaps, we first need to know about them. Then we need to find some
other solution than a blanket blacklist of all fonts with EBDT tables.
For instance, we could separate the bitmap glyphs into their own QGlyphRuns
and use native rendering only for those specific glyphs.
[ChangeLog][Windows][Fonts] Some key fonts, such as Calibri, were being
detected as bitmap fonts and not rendered correctly in Qt Quick. This has
now been fixed.

When a black font is used, such as Arial Black, it would cause
the font to appear to be rendered twice, particularly at large
point sizes. This is down to the synthesizing of the bold
aspect, however since the font is actually weighted as black
this is not required.

Looks up the canonical names of enumerated fonts and register them under
their preferred names if present.
Also changes the logic handling registration of english aliases, so it
is always done, even if it might in rare cases cause a double
registration since that is safe.

This allows creating or extending QPA plugins to provide access to QFont
and related types.
It concerns both GDI and DirectWrite engines, as well as the regular and
the freetype based font databases. The qt.qpa.fonts logging category has
been moved together into the QWindowsFontDatabase related files to avoid
depending on the qwindowscontext.h header file. Finally, QwindowsNativeImage
is following pending a future refactor with similar code in qpixmap_win.cpp
and the Windows XP style.
