Since 2024-02-09 or so this test frequently times out on a few of our
Windows CI runners. Use fewer but longer command lines to achieve a
similar total command length. By running fewer commands, the test
takes much less time.
Ninja runs just one command line for every build statement, so the Ninja
generator needs to `&&`-chain multiple commands together into one long
string. For long custom command sequences this can exceed the maximum
command-line length for the operating system. In such cases, write the
commands out to a script instead, and then run the script from Ninja's
one command line.
