[clang][Driver] Add -fuse-lipo option (#121231)
Partially fixes https://github.com/llvm/llvm-project/issues/59552 by
adding a new option `-fuse-lipo` that can specify the tool name to be
used by clang-driver for the lipo action. For example, pass
`-fuse-lipo=llvm-lipo` to use `llvm-lipo` instead of the default `lipo`.
