[CMake] Bump CMake minimum version to 3.13.4

This upgrade should be friction-less because we've already been ensuring that CMake >= 3.13.4 is used. This is part of the effort discussed on llvm-dev here: http://lists.llvm.org/pipermail/llvm-dev/2020-April/140578.html Differential Revision: https://reviews.llvm.org/D78648
