Add support for building Windows x64 fullaot version of winaot profile
that can be run on CI. Initial changes also add execution of mini regression
tests on CI. More tests will be added going forward and when having full
pass rate.
Add support for building Windows x64 fullaot+llvm version of winaot profile
that can be run on CI. Initial changes also add execution of mini regression

In order to get deterministic build results and working build on CI, we need
to setup a correct build environment for the MSVC builds. Since MSVC build is
currently run from cygwin, there are environment problems, both general
but also in our CI environment, since we add cygwin bin folder to system path
(needed by Jenkins plugin). When running more complex cmake builds like
BTLS and LLVM, this will cause problems picking up incorrect tools,
failing builds on CI.
Another problem is the AOT compilation using MSVC toolchain. In the
past CI used some "hard coded paths" to make sure clang.exe and link.exe was found.
This is not optimal and won't work when including LLVM as part of full AOT since
link.exe will need access to more of the full build environment setup by VS
development environments (like platform libraries).
In order to get a better build environment on CI this commit includes and enhance
a couple of build scripts used to run msbuild.exe and mono-sgen.exe (as AOT compiler)
in a VS development environment, isolate that build process from cygwin environment.
The build scripts will locate installed VS tooling, VS2015 build tools or VS dev env,
VS2017 build tools or VS dev env and use corresponding development environment
scripts as part of running msbuild.exe and mono-sgen.exe in AOT mode.
In order to make sure mono-sgen.exe as AOT compiler is run through these scripts
an additional environment variable MONO_EXECUTABLE_WRAPPER is introduced and used
in mono-wrapper when set. Without this indirection there will be problems on CI
tests since the environment is using MONO_EXECUTABLE and pass that into for example
test driver that run child processes of mono-sgen.exe, meaning that we can't
use scripts for MONO_EXECUTABLE, but splitting the MONO_EXECUTABLE to represent
mono runtime and have a MONO_EXECUTABLE_WRAPPER that could be a launch script
solves this issue.
This commit also includes several smaller fixes made to the generic
fullaot build infrastructure.
Fix additional msbuild arguments.
Add Mono.SIMD assembly to winaot profile.
Run msbuild.exe as part of .bat file.
