[lldb][Windows] reconfigure project in the correct directory (#206781)
Currently, the second reconfigure fails with `CMake Error: The source
directory "C:/workspace/llvm-project" does not appear to contain
CMakeLists.txt.`.
This patch copies the full cmake invocation to properly reconfigure the
project with `LLDB_TEST_USE_LLDB_SERVER=1`.
This is a follow up to https://github.com/llvm/llvm-project/pull/206511.
