7d73e88d3a MSVC: Revert "Default to -ZI instead of /Zi for x86 and x64"
Revert commit 5fcadc481e (MSVC: Default to -ZI instead of /Zi for x86
and x64, 2022-05-24).  The `-ZI` flag is incompatible with the `-GL`
flag used for IPO, and so is not an unconditionally better default.
Revert the change pending future design of a first-class setting for
MSVC debug info format that can be automatically reconciled with IPO
settings.

That commit introduced policy CMP0138, but we already have later policy
numbers used too.  Leave placeholder text to avoid policy renumbering.

2c71d051fa Makefiles Generators: use compiler for dependencies generation
Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.

The consolidation uses the same approach as `CMake` dependencies management.

Initializer lists are only properly supported in 2015 and above.
Previous Visual Studio releases said they supported initializer lists
but silently produced bad code.

216afc8a81 MSVC: Add /FS flag for cl >= 18 to allow parallel compilation (#14492)
In generators such as Ninja that can run multiple "cl" processes that
refer to the same compiler .pdb file (/Fd) at the same time, MSVC from
Visual Studio 2013 complains:

 fatal error C1041: cannot open program database '.../vc120.pdb';
 if multiple CL.EXE write to the same .PDB file, please use /FS

According to "cl /?":

 /FS force to use MSPDBSRV.EXE

Add the flag to compilation lines for this compiler version just after the
/Fd option.

f3ddfef137 Modernize MSVC compiler information files
Remove the old-style "Windows-cl.cmake" and its helper "cl.cmake".  Load
the information through new-style "Platform/Windows-MSVC-<lang>.cmake"
files.  Factor information common to C and CXX into a helper file
"Platform/Windows-MSVC.cmake" loaded from the per-language files.
