This uses llvm-lib.exe for the librarian instead of Visual Studio
provided lib.exe. Without this it is not possible to create static
libraries with -flto using the plugin.

This patch removes the MSBuild warnings about options that
clang-cl ignores. It also adds several additional fields to
the LLVM Configuration options page. The first is that it
adds support for LLD! To give the user flexibility though,
we don't want to force LLD to always-on, and if we're not
forcing LLD then we might as well not force clang-cl either.
So we add options that can enable or disable lld, clang-cl,
or any combination of the two. Whenever one is disabled,
it falls back to the Microsoft equivalent.
Additionally, for each of clang-cl and lld-link, we add a new
configuration setting that allows Additional Options to be
passed for that specific tool only. This is similar to the
C/C++ > Command Line > Additional Options entry box, but
it serves the use case where a user switches back and forth
between the toolsets in their vcxproj, but where cl.exe
won't accept some options that clang-cl will. In this case
you can pass those options in the clang-cl additional options
and whenever clang-cl is disabled (or the other toolset is
selected entirely), those options won't get passed at all.

Normally we force Unix line endings in the repository, but since these are Windows files which are consumed by Microsoft tools that we don't have the source of, we should probably err on the side of caution and force CRLF.

We do need to map /Zi to /Z7 explicitly for msbuild as explained in this file,
but since /Zi is passed by default and since things transparently work fine
with it mapped to /Z7, we shouldn't produce effectively inactionable noise for
it.
Also don't warn on /X since clang-cl supports that (since r326357; the risk of
duplicating a bunch of clang-cl driver logic here).

This is a new modernized VS integration installer. It adds a
Visual Studio .sln file which, when built, outputs a VSIX that can
be used to install ourselves as a "real" Visual Studio Extension.
We can even upload this extension to the visual studio marketplace.
This fixes a longstanding problem where we didn't support installing
into VS 2017 and higher. In addition to supporting VS 2017, due
to the way this is written we now longer need to do anything special
to support future versions of VS as well. Everything should
"just work". This also fixes several bugs with our old integration,
such as MSBuild triggering full rebuilds when /Zi was used.
Finally, we add a new UI page called "LLVM" which becomes visible
when the LLVM toolchain is selected. For now this only contains
one option which is the path to clang-cl.exe, but in the future
we can add more things here.
