builtin/add.c: replace run_command() with direct apply_all_patches() call

When the user runs "git add -e", the diff of the working tree changes is written to a temporary file, opened in an editor, and then applied back to the index. The application step is done by spawning a child process running "git apply --recount --cached <file>", which is an unnecessary subprocess since the apply machinery is available as a native C API. Replace the run_command() call with a direct call to apply_all_patches() using an initialized apply_state with the cached and recount options set appropriately. This avoids the overhead of forking a subprocess, keeps the operation within the same process, and makes the intent of the code clearer to the reader. Remove the now-unused includes of "run-command.h" and "strvec.h" since no other code in this file requires them after this change.
