windows-msi: add vcruntime.dll

Since we start to build releases with MSVC,
(and for ARM64 this is the only option), VC runtime library
needs to be bundled. The recommended way to include it is to use MSMs:

  https://devblogs.microsoft.com/cppblog/how-to-redistribute-the-visual-c-libraries-with-your-application/

However as for now there is no MSM for ARM64 available, so we do
"app-local" deployment and copy required DLL (vcruntime140.dll) to
bin directory.

DLLs were obtainted from:

  C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Redist\MSVC\14.29.30036
