PR #1699: Add option to build with MSVC static runtime
Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1699
The correct CMake policy is set, but there is no option to switch the msvc runtime when configuring the project.
Since MSVC is a multiconfiguration build tool, we need to set this CMake variable internal to the project to ensure that all of the supported build configurations get properly set (i.e. `Release` builds use `/MT` or `/MD` and `Debug` builds use `/MTd` or `/MDd`).
I tried to explictly set these flags (i.e. -DCMAKE_CXX_FLAGS_XXX) when configuring the project, but these flags were being overwritten due to [explicitly setting compiler flags](https://github.com/abseil/abseil-cpp/blob/master/CMake/AbseilHelpers.cmake#L285).
