[cmake] Limit missing external lit warning to be shown once
When using a custom `LLVM_EXTERNAL_LIT`, it's possible the file may not exist at the CMake is generating the build. One example is LLDB standalone builds. When the external lit doesn't exist, a warning message is emitted, but the warning is printed once for every single lit target. This produces many redundant warnings.
This changes the warning to only be emitted once, controlled by a CACHE variable.
Other options are:
1. remove the warning
2. have callers pass an option to silence the warning if desired
See https://reviews.llvm.org/D76945 for some context.
