LOG: [llvm][SandBoxIR] Fix Windows+clang compiler warning (#146905)

C:\Users\tcwg\llvm-worker\lldb-aarch64-windows\llvm-project\llvm\include\llvm/SandboxIR/Value.h(172,16):
warning: unqualified friend declaration referring to type outside of the
nearest enclosing namespace is a Microsoft extension; add a nested name
specifier [-Wmicrosoft-unqualified-friend]

Clang suggests adding ::llvm::, but:
* Region is in ::llvm::sandboxir
* Region is not defined at this point

So forward declare it.

Added: 
    

Modified: 
    llvm/include/llvm/SandboxIR/Value.h

Removed:
