thermal: netlink: Fix compilation error when CONFIG_NET=n

When the network is not configured, the netlink is disabled on all
the system. The thermal framework assumed the netlink is always
opt-in.

Fix this by adding a Kconfig option for the netlink notification,
defaulting to yes and depending on CONFIG_NET.

As the change implies multiple stubs and in order to not pollute the
internal thermal header, the thermal_nelink.h has been added and
included in the thermal_core.h, so this one regain some kind of
clarity.
