Setting of these security params is duplicated in multiple parts of the
wifi stack. So, centralize this.
a) Move the security type enum from ScanResultMatchInfo class internally
into WifiConfiguration. (Note: Values don't change, just the name & location
since this is being persisted in multiple places)
b) Add a helper method to set the various security params required for
each security type.
Also, removed setting defaults in WifiNetworkSpecifier &
WifiNetworkSuggestion. This will anyway be handled by WifiConfigManager
on network addition. There is no need to replicate this in the API
surface.
