According to latest clang source code (llvm-14.0.3) non-fragile ABI
is default for everything but i386 which means we can stop passing the
-fobjc-nonfragile-abi option.
See
https://github.com/llvm/llvm-project/blob/llvmorg-14.0.3/clang/lib/Driver/ToolChains/Darwin.h#L245
This gets rid of the following warning when building a qmake project
for iOS, while targeting the iOS simulator:
clang: warning: argument unused during compilation:
'-fobjc-nonfragile-abi' [-Wunused-command-line-argument
It only happens for the simulator case because Xcode adds the
-fobjc-abi-version=2 option, thus the qmake one gets ignored.
As a drive-by also remove the usage of the -fobjc-legacy-dispatch
option. According to clang sources it should be implicitly used
on iOS.

All of these flags were blindly copied from Xcode and all of them are
not needed because they are unnecessary or at the very least are for no
reason specific to iOS/tvOS/watchOS.
* -fvisibility=hidden,
-fvisibility-inlines-hidden - handled in common/gcc-base.conf
* -fpascal-strings - a Mac OS Classic legacy, no one uses these
* -fmessage-length=0 - formatting option, not needed
* -fexceptions, -fasm-blocks - these are on by default and not needed
All explicitly enabled warnings are enabled by -Wall, which is handled
in common/gcc-base.conf. All explicitly disabled warnings should not be
disabled because we simply do not do this anywhere else in qmake.

These actually affect all UIKit platforms (tvOS, watchOS), not just iOS.

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.
