Mostly mechanical changes in preparation of extracting the Flang-RT "subproject" in #110217. This PR intends to only move pre-existing files to the new folder structure, with no behavioral change. Common files (headers, testing, cmake) shared by Flang-RT and Flang remain in `flang/`. Some cosmetic changes and files paths were necessary: * Relative paths to the new path for the source files and `add_subdirectory`. * Add the new location's include directory to `include_directories` * The unittest/Evaluate directory has unitests for flang-rt and Flang. A new `CMakeLists.txt` was introduced for the flang-rt tests. * Change the `#include` paths relative to the include directive * clang-format on the `#include` directives * Since the paths are part if the copyright header and include guards, a script was used to canonicalize those * `test/Runtime` and runtime tests in `test/Driver` are moved, but the lit.cfg.py mechanism to execute the will only be added in #110217.
