LOG: [Flang][CMake] Use LLVM-declared LLVM_EXTERNAL_LIT (#208680)

LLVM_EXTERNAL_LIT is already declared by
https://github.com/llvm/llvm-project/blob/99fb741b6e0da866bf3c6000531104bff347d787/llvm/cmake/modules/AddLLVM.cmake#L2175.
Flang's redeclaration in standalone builds is redundant and breaks on
Windows because the filename there is `llvm-lit.py`.

Added: 
    

Modified: 
    flang/CMakeLists.txt

Removed:
