main: Change the register_argc_argv INI default to Off

[TimWolla]

This partly implements the deprecation of the register_argc_argv INI setting by updating the default value to ensure safe behavior when no INI file is loaded. The actual deprecation warning will follow separately, since it is non-trivial to implement with the desired per-SAPI behavior.

@cmb69 Any idea for the Windows-specific failure?

[cmb69]

The --INI-- section is ignored on Windows, due to 9382673. Simplest solution would be to modify the test so the query string contains an equals sign:
