After we stopped sanitizing the fallback font list (with change
6ca48a847a), we now need to make
sure it is ordered so that the fonts that support the writing
system in question are always tested first, otherwise we can end up
loading a lot of fonts that will never be used.

When we request fallback fonts, we cannot discriminate the fonts
based on the writing system support. This is especially important
since common script is now merged with other scripts, meaning that
a common script character will always go through the fallback
mechanism when not supported by the main font. When drawing
for instance a string of Devanagari characters on macOS, we would
get a list of 33 fallback fonts, but almost all of them would be
the default Devanagari font, since none of the other fallbacks
would support that script. Meaning that we would just check the
same font over and over, which makes no sense. The fallback list
has been retrieved specifically for the given script, so we do
not need to consider that when fetching the fonts.
For most of the common set, we will not have noticed the bug,
because at least one of the writing system-specific fallbacks will
have had support for latin characters as well. But when trying to
mix emojis and some non-common script, we would get a box in
place of the emoji, which had been adopted to the main script and
would only be looked for in the fonts supporting this.
Note that this exposed an issue with the QRawFont test on some
systems. When the sample text contained a space, it would
be possible to get a fallback font for this character, since
we now effectively support fallbacks. This is not the correct
behavior, but it is unrelated to this fix, and it was not what
the QRawFont::unsupportedWritingSystem() test was written to
check. I have therefore removed the space from the sample text
to make the test pass, and will make a separate task of fixing
the issue of merging fonts for whitespace characters.
[ChangeLog][QtGui][Text] Fixed a bug where mixing different
writing systems with emojis could lead to missing glyphs.

When calculating the width of a text for drawing decorations on top,
we use the effective advance of the whole text after it has been
through the shaper.
However, in the case of QStaticText and QGlyphRun, there is shortcut:
Since we only have the glyph indexes and position of each glyph,
we use the position + advance of the right-most glyph to find the
right-most edge of the decoration. For this, however, we use the
advance of the glyph *out of context* of the rest of the string,
because the whole idea is to avoid doing the shaping of the string
with every draw call. In some rare cases, the advance of the
right-most character, in the context of the string, is different
from the advance of the standalone glyph.
Now, one way of fixing this would be to store the width of the
text in QStaticText and QGlyphRun, but since it is a very rare
artifact which is barely visible, I have opted to just work around
it in the test instead, the workaround being to force integer
metrics so that we don't get the small 0.2 pixel error.

Commit 2bc7a40048 taught the CoreText font database to populate the
families lazily, and in the process added a guard to ensure that we
didn't populate internal fonts (prefixed with a '.'), as these fonts
would then show up in font selection dialogs.
Commit 909d3f5c7 then added support for private fonts, by making it
possible to filter out any private fonts from font selection daialogs.
But the guard was not removed, so we were still not populating these
fonts. This guard has been removed, and the filtering function has
been updated to include the conditions of the guard.
Next, commit e5e93345c5 used [UIFont fontNamesForFamilyName:] to verify
that each family that we registered with the font database would also
have matching fonts when finally populated. This is not the right approach,
as [UIFont fontNamesForFamilyName:] does not handle internal fonts.
Instead we trust what CTFontDescriptorCreateMatchingFontDescriptors()
gives us, but make sure to register the resulting font descriptors
with the original/originating font family, instead of the one we pull
out of the font descriptor.
Finally, as of iOS 10, we can use CTFontManagerCopyAvailableFontFamilyNames
instead of [UIFont familyNames], which gives us all of the internal font
families like on macOS, instead of just the user-visible families. For
earlier iOS versions we manually add '.PhoneFallback', as we know it
will be available even if not listed in [UIFont familyNames].
The end result is that we register and populate families like '.PhoneFallback',
which is critical to supporting more esoteric writing systems.
The check in tst_QFont that styles for a given family is not empty has
been removed, as we can't guarantee that on all platforms, which is
also documented for QFontDatabase::styles().

This caused the font dialog to list unsupported sizes for bitmap

We would also claim to support creating bitmap fonts at

1. QFontInfo(font).pointSize() would return the requested size,
not the actual rendered size.
2. Bitmap fonts created at 64 pixels and higher would be invisible.
On Mac, there are no system bitmap fonts, and the use is not very
