Microbuild support for F# codebase

[OmarTawfik]

This PR Includes

• Moving localization/signing process to Microbuild.
• Stamping all binaries/executables produced by version number and build date.
• Separating project and item templates into separate projects.
• adding microbuild-everything.proj that builds all binaries on all platforms supported.
• Removing support for 9055 OSS version (depending on the new build stamps now).

What is MicroBuild? Is it open source? Is it the new MSBuild? I noticed this uses MicroBuild.Core 0.2.0. I see that it is uploaded both places:

https://dotnet.myget.org/gallery/dotnet-buildtools
https://www.nuget.org/packages/MicroBuild.Core/

Looks great ... ship it :-)

@ctaggart Microbuild is the thing that gets us out of the big VS build process internally. It is a step towards removing all of that internal machinery we now have to worry about.

For example after this change our internal product build will not have a separate set of project files. Which was always embarrassing but unavoidable.

There are a mix of forward and backslashes here

@otawfik-ms After this commit incremental builds seem to be broken?

On master, when I do build all, all projects now get recompiled, right from proto. I suspect it's because of the generation of the AssemblyFileVersion file:

        Generating AssemblyFileVersion file: C:\Users\dsyme\AppData\Local\Temp
        \tmp8911.tmp.fs

It's really important to fix this to enable contributors to be productive in their build+tests

Nit: indentation looks off here.

@dsyme I believe the failures are related to the recent coreclr changes, not microbuild, which is being fixed now in a separate location.
