Reduce requirements for running homebrew (#1053)

* Reduce requirements for running homebrews

This commit change the following behaviours:

- TimeZoneBinary system archive isn't required until guest code call LoadTimeZoneRule.
- Fonts system archives aren't requred until a "pl:u" IPC call is made.
- Custom font support was dropped.
- TimeZoneBinary missing message is now an error and not a warning.

* Address comments
