Merge all "win32-msvc*" mkspecs into one

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).
