[minigraph.py]: Enable 400G to 100G/40G speed change via minigraph for all platforms (#14736)

Browse Source 
There are chassis-packet and Single asic platforms which support this 400G to 100G/40G speed change via config.
Enabling this feature for all platforms which can support this. Keeping it enabled for all does not affect the platforms
which do not support this feature yet.
