[Feature]: Allow tree shaking of @internationalized/date

[Solant]

Describe the feature

File /packages/core/src/shared/date/comparators.ts imports createCalendar from @internationalized/date package, which leads to all calendars being included in resulting application bundle

Additional information

• I intend to submit a PR for this feature.
• I have already implemented and/or tested this feature.

Hm, the problem is that the default has to be createCalendar in order to pick the appropriate calendar without requiring people to deal with picking the right impl 😕

Using the Gregorian calendar as a default means locales which use another calendar system won't have the proper calendar show up without additional logic, but at the same time it's right it's a waste to include all calendar systems if only one ends up in use.

Besides a build-time flag I'm unsure this can easily be solved without downgrading i18n handling

Hey

I'm not sure if locale corresponds with the calendar system (in my opinion Gregorian is somewhat default in any case, but I can be wrong at this one)

Is it possible to use a provider to pass all possible calendar systems and locales?
