New configure options:

Qt couldn't be configured with -system-zlib on macOS, because qmake
failed to find "/usr/lib/libz.dylib".
The library path is something along the lines of
"/Applications/Xcode.app/.../MacOSX10.14.sdk/usr/lib" which doesn't
contain "libz.dylib". But it contains "libz.tbd", which is a YAML-file
pointing to "/usr/lib/libz.dylib". One can pass the absolute path to
this tbd file to the linker, which will then pick up
"/usr/lib/libz.dylib".
Introduce a new variable QMAKE_EXTENSIONS_AUX_SHLIB, which is a list
of auxiliary extensions for shared libs, and add the "tbd" extension
to it on macOS.

3) export QT_VULKAN_LIB=/path/to/MoltenVK/Package/Release/MoltenVK/macOS/libMoltenVK.
Implement support for QSurface::VulkanSurface by enabling

MoltenVK provides an implementation of the Vulcan API,

Neither the Intel compiler nor Visual C++ have a dedicated switch to
enable F16C support, like GCC and Clang do. So we used the AVX switch
for that in commit 8241d51f70, as it was
the closest, lowest denominator. That was incorrect and insufficient.
The Intel compiler silently miscompiles the intrinsics with -xAVX,
making calls to out-of-line functions like _mm_cvtps_ph, which don't
exist. So we actually have to use AVX2 support to generate correct code.
That might be a problem later, since Ivy Bridge supports F16C but not
AVX2.
Visual C++ is able to generate F16C code with just -arch:AVX.
Either way, since there's no dedicated command-line switch, there's also
no dedicated preprocessor macro. We're using __AVX2__ for both
compilers, as that's a sufficient condition to indicate a processor that
supports F16C.

The AES instructions were first introduced with the Westmere shrink

pending on Intel architecture, but is available on AMD family 17h (gcc
argument -march=znver1).
Both features operate on SSE registers, so that's why the MSVC command-
line argument is the SSE2 one and the configure-time tests depend on
features.sse2.
The qmake feature names end in "ni" because "aes" and "sha" are too
simple and could clash with other uses. The QT_COMPILER_SUPPORTS_ macro
doesn't have the "NI" suffix because it has to match the GCC/Clang
predefined macro.

Since we can tell the MSVC version from the compiler now, each of the
qmake.conf files is now the same, so let's just have "win32-msvc" and be
future-proof. Likewise for win32-clang-msvc.
qplatformdefs.h was already common.
Since we can't obtain the MSVC version from the unified mkspec name any
more, I dropped the warning level during the qmake bootstrap to reduce
the number of warnings that need to be disabled from compiler version to
version.
There is no point in keeping the old mkspecs, but configure will re-map
the -platform argument to the unified spec as necessary, to keep
existing configure command lines working.
[ChangeLog][Visual Studio] Qt now has a common mkspec for all Visual
Studio versions, called "win32-msvc". The old names which contained the
version number are now gone (but qmake scopes based on the old names
continue to work). The version of the compiler can be obtained from the
MSC_VER and MSVC_VER variables (for example, for Visual Studio 2015,
those contain the values 1900 and 14.0, respectively). Those variables
are also available with the Intel compiler (win32-icc) and with Clang
(win32-clang-msvc).

This is needed in order to be able to specify a custom location of
the ANGLE libs, and enables us to perform a LoadLibrary of ANGLE libs
by just having the absolute path to QtANGLE.dll as the argument to
LoadLibrary().
Previously, we had two ANGLE libraries: libEGL and libGLESv2. libEGL hard
linked against libGLESv2. If we wanted to load libEGL from a custom
location, we couldn't load libEGL by calling LoadLibrary with the absolute
path to libEGL, because libEGL had problems finding libGLESv2. One
solution to that could have been to call SetDllDirectory() with the path
to the ANGLE libs before calling LoadLibrary("libEGL.dll"). Since the DLL
directory would point to both ANGLE libs, this would ensure that the libGLESv2
was also found. Unfortunately, this approach is not thread safe
(SetDllDirectory will affect all subsequent LoadLibrary(Ex) from the same
process). Therefore, we chose to merge the two libraries into one to
circumvent the whole problem.
At the same time, this patch also enables loading of two different ANGLE
libraries into the same process at once without renaming them: This was
not possible before because libEGL hard linked to libGLESv2.dll. When
libGLESv2.dll was already loaded, the second instance of libEGL would
simply link against the already loaded version of libGLESv2.dll.
This behavior is documented in the LoadLibraryEx documentation on MSDN:
"If the string specifies a module name without a path and more than one
loaded module has the same base name and extension, the function returns a
handle to the module that was loaded first."
