[Macros] Type check user-defined macro plugins (#61861)

Browse Source 
Type check user-defined macros plugins with user-provided type signatures.

Also, load plugin libraries with `RTLD_LOCAL` instead of `RTLD_GLOBAL` to prevent symbol collision between plugins. `llvm::sys::DynamicLibrary` only supports `RTLD_GLOBAL` so we use the plain `dlopen` instead. This does not work on Windows and needs to be fixed.
