msvc: support building Git using MS Visual C++

With this patch, Git can be built using the Microsoft toolchain, via:

	make MSVC=1 [DEBUG=1]

Third party libraries are built from source using the open source
"vcpkg" tool set. See https://github.com/Microsoft/vcpkg

On a first build, the vcpkg tools and the third party libraries are
automatically downloaded and built. DLLs for the third party libraries
are copied to the top-level (and t/helper) directory to facilitate
debugging. See compat/vcbuild/README.

A series of .bat files are invoked by the Makefile to find the location
of the installed version of Visual Studio and the associated compiler
tools (essentially replicating the environment setup performed by a
"Developer Command Prompt"). This should find the most recent VS2015 or
VS2017 installation. Output from these scripts are used by the Makefile
to define compiler and linker pathnames and -I and -L arguments.

The build produces .pdb files for both debug and release builds.

Note: This commit was squashed from an organic series of commits
developed between 2016 and 2018 in Git for Windows' `master` branch.
This combined commit eliminates the obsolete commits related to fetching
NuGet packages for third party libraries. It is difficult to use NuGet
packages for C/C++ sources because they may be built by earlier versions
of the MSVC compiler and have CRT version and linking issues.

Additionally, the C/C++ NuGet packages that we were using tended to not
be updated concurrently with the sources.  And in the case of cURL and
OpenSSL, this could expose us to security issues.

The Steps to Build Git with VS2015 or VS2017 from the command line.
1. Install the "vcpkg" open source package manager and build essential
third-party libraries. The steps for this have been captured in a
set of convenience scripts. These can be run from a stock Command
Prompt or from an SDK bash window:
$ cd <repo_root>
$ ./compat/vcbuild/vcpkg_install.bat
The vcpkg tools and all of the third-party sources will be installed
in this folder:
<repo_root>/compat/vcbuild/vcpkg/
A file will be created with a set of Makefile macros pointing to a
unified "include", "lib", and "bin" directory (release and debug) for
all of the required packages. This file will be included by the main
Makefile:
<repo_root>/compat/vcbuild/MSVC-DEFS-GEN
2. OPTIONALLY copy the third-party *.dll and *.pdb files into the repo
root to make it easier to run and debug git.exe without having to
manipulate your PATH. This is especially true for debug sessions in
Visual Studio.
Use ONE of the following forms which should match how you want to
compile git.exe.
$ ./compat/vcbuild/vcpkg_copy_packages.bat debug
$ ./compat/vcbuild/vcpkg_copy_packages.bat release
3. Build git using MSVC from an SDK bash window using one of the
following commands:
$ make MSVC=1
$ make MSVC=1 DEBUG=1
================================================================
The Steps of Build Git with VS2008
1. You need the build environment, which contains the Git dependencies

@ECHO OFF
REM ================================================================
REM You can use either GCC (the default) or MSVC to build git
REM using the GIT-SDK command line tools.
REM $ make
REM $ make MSVC=1
REM
REM GIT-SDK BASH windows inherit environment variables with all of
REM the bin/lib/include paths for GCC. It DOES NOT inherit values
REM for the corresponding MSVC tools.
REM
REM During normal (non-git) Windows development, you launch one
REM of the provided "developer command prompts" to set environment
REM variables for the MSVC tools.
REM
REM Therefore, to allow MSVC command line builds of git from BASH
REM and MAKE, we must blend these two different worlds. This script
REM attempts to do that.
REM ================================================================
REM This BAT file starts in a plain (non-developer) command prompt,
REM searches for the "best" commmand prompt setup script, installs
REM it into the current CMD process, and exports the various MSVC
REM environment variables for use by MAKE.
REM
REM The output of this script should be written to a make "include
REM file" and referenced by the top-level Makefile.
REM
REM See "config.mak.uname" (look for compat/vcbuild/MSVC-DEFS-GEN).
REM ================================================================
REM The provided command prompts are custom to each VS release and
REM filled with lots of internal knowledge (such as Registry settings);
REM even their names vary by release, so it is not appropriate for us
REM to look inside them. Rather, just run them in a subordinate
REM process and extract the settings we need.

REM -------------------
REM Visual Studio 2017 introduced a new installation layout and
REM support for side-by-side installation of multiple versions of
REM VS2017. Furthermore, these can all coexist with installations
REM of previous versions of VS (which have a completely different
REM layout on disk).
REM
REM VS2017 Update 2 introduced a "vswhere.exe" command:
