rename NET to NET_LEGACY

Browse Source 
Highlight that NET really is the legacy networking stack by renaming the
option to NET_LEGACY.

This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise
CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL.

The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is
using the legacy networking app so this seems fine to do.

This also has the benefit of removing potential confusion on NET being a
specific networking stack instead of "any" network stack.
