timezone: Fix regression caused by #3361 (#3418)

Browse Source 
Because of that PR, TimeZoneRule was bigger than 0x4000 thanks to a
misuse of a constant.

This commit address this issue and add a new unit test to ensure the size of
TimeZoneRule is 0x4000 bytes.

Also address suggestions that were lost on the original PR.
