WifiConfigManager: rename member and constant fields

Rename fields in WifiConfigManager to properly reflect that
they are members (m* prefix), and constants (all caps with
underscores). To accomodate this change, also modify uses
of these fields outside WifiConfigManager (e.g. in WifiStateMachine).

Also:
- Remove default values given to WifiConfigManager member fields
  that are initialized in its constructor, since the initalization renders
  the default values useless.
- Remove member fields and constants that are unused.
- Replace the "*Milli" suffix on fields with "Ms".
- Re-ordered fields in a logical manner (i.e. static, public, then
  private).
- Fixed checkstyle issues.
