  [C++20] [Modules] Serialize the evaluated constant values for VarDecl

Close https://github.com/llvm/llvm-project/issues/62796.

Previously, we didn't serialize the evaluated result for VarDecl. This
caused the compilation of template metaprogramming become slower than
expect. This patch fixes the issue.
