There's no reason for this to be separated, regardless of the
support status of i386 macOS builds. Additional architectures may
appear in the future (and currently there's actually 3 - i386,
x86_64, and x86_64h for Haswell CPUs). So this feature could be
used to get combined generic x86_64 and Haswell builds. Some
system libraries appear to have an x86_64h slice in Sierra.
[ChangeLog][Build System] Support for universal binaries on macOS
has been re-introduced.

This reduces unnecessary OS conditions in qmake since these platforms
are mutually exclusive, and also opens up their potential for use on
future devices (like carOS(?), which is device idiom '5').
This is also more similar to what Xcode does, as the
TARGETED_DEVICE_FAMILY variable is not platform specific.

This reduces unnecessary OS conditions in qmake since these platforms
are mutually exclusive, and also opens up their potential for use on
macOS to transparently support multi-arch builds like UIKit platforms.
This is also more similar to what Xcode does, as the DEPLOYMENT_TARGET
variables are platform specific, while the ARCHS variable is not.
DEPLOYMENT_TARGET has a use case for being OS specific in qmake (host
tools vs targets), while ARCHS does not.

This patch moves towards a more sensible layout for UIKit platforms,
where both the device and simulator architectures for binaries are
combined into a single Mach-O file instead of separating out the
simulator architecutures into separate _simulator.a files.
This approach is both more common in the iOS ecosystem at large and
significantly simplifies the implementation details for Qt, especially
with the upcoming support for shared libraries on UIKit platforms.
This patch takes advantage of the -Xarch compiler option to pass the
appropriate -isysroot, -syslibroot, and -m*-version-min compiler and
linker flags to the clang frontend, operating in exactly the same way
as a normal multi-arch build for device or simulator did previously.
Exclusive builds are still enabled for the xcodebuild wrapper Makefile,
which builds all four configurations of a UIKit Xcode project as before,
as expected.
A particularly advantageous benefit of this change is that it flows very
well with existing Xcode workflows, namely that:
- Slicing out unused architectures is handled completely automatically
for static builds, as an executable linking to a library with more
architectures than it itself is linked as, the unused architectures
will be ignored silently, resulting in the same behavior for users
(and the App Store won't let you submit Intel architectures either).
- Removing architectures from a fat binary using lipo does NOT
invalidate the code signature of that file or its container if it is a
bundle. This allows shared library and framework builds of Qt to work
mostly automatically as well, since an Xcode shell script build phase
can remove unused architectures from the embedded frameworks when that
is implemented, and if Qt ever starts signing its SDK releases, it
won't interfere with that either (though binaries are just resigned).

The actual blocker for precompiled headers is not the iOS/tvOS/watchOS
platforms, but the way qmake handled multiple-architecture builds on
Apple platforms.
This patch allows multi-arch builds to be performed while using
precompiled headers.
Since df91ef3d6c55692a0236f67b6c6b134a3bf84098 (April 2009), Clang has
had support for PCH files in the driver, which allows to use the
-include flag to automatically translate to -include-pch. We can then
take advantage of the fact that the -include option is allowed to not
be separate from its argument, which lets us take advantage of -Xarch to
specify a per-architecture precompiled header file.
This is done through some magic in the qmake Makefile generator which
"multiplexes" the PCH creation rule across multiple architectures and
replaces a series of tokens with the proper precompiled header paths
and architecture flags at usage point.

Pass -xplatform macx-tvos-clang to configure to build.
Builds device and simulator by default.
Added ‘uikit’ platform with the common setup.
Also added QT_PLATFORM_UIKIT define (undocumented).
qmake config defines tvos (but not ios).
tvOS is 64bits only (QT_ARCH is arm64) and requires bitcode to be
embedded in the binary. A new ‘bitcode’ configuration was added.
For ReleaseDevice builds (which get archived and push to the store),
bitcode is actually embedded (-fembed-bitcode passed to clang). For all
other configurations, only using bitcode markers to keep file size
down (-fembed-bitcode-marker).
Build disables Widgets in qtbase, and qtscript (unsupported,
would require fixes to JavaScriptCore source code).
Qpa same as on iOS but disables device orientation, status bar, clipboard,
menus, dialogs which are not supported on tvOS.

- moved prf files to shared location (uikit, added to QMAKE_PLATFORM)
- prepare some formatting (unconditional blocks mostly) to add conditions later
- make device detection script more generic, passing filter strings
as a parameter and returning non-os specific variables
