Port of ma_test_force_start.pl (test program for --maria-force-start-after-recovery-failures) to Windows.

storage/maria/ma_test_force_start.pl:
  port to Windows: detection of where 'mysql' command-line client is (debug/release/etc)), .exe suffix,
  --console instead of --mem, --P instead of --socket, taskkill instead of perl's kill.
