feat: Add timezone location support

[deelawn]

Closes #2688.

The PR adds support for timezone locations by embedding an IANA timezone database that gets loaded into memory when gno.land is started. The gno stdlib's time package has been updated by porting over code from the go stdlib to support locations.

This feature allows users to create time instances with locations to ensure that temporal adjustments result in accurate results by following both historical rules and current rules.
