Adapt compilerplugins to LLVM 13 APSInt::toString change

<https://github.com/llvm/llvm-project/commit/61cdaf66fe22be2b5942ddee4f46a998b4f3ee29>
"[ADT] Remove APInt/APSInt toString() std::string variants".

TODO:  While most uses of compat::toString should be harmless performance-wise,
as they are either in error reporting code or in plugins that are not run by
default, some calls like the one in compilerplugins/clang/staticconstfield.cxx
might benefit from moving them away from using std::string.
