extensions: Relocate pref name constants.

Move extension-related pref name constants used by the
ExtensionPrefs class from chrome/common/pref_names.h to
extensions/browser/pref_names.h. Remove "Extension" from the
beginning of the constant identifiers and "Pref" from the
end since it seemed redundant now that they're in the
extensions::pref_names namespace.

Also delete prefs::kExtensionBlacklistUpdateVersion since it
hasn't been used in about a year.
