Add comprehensive API support for 1.21.x features

[ghost]

Summary

This Pull Request introduces comprehensive API support for several missing 1.21.x features, providing developers with better control over the latest Minecraft mechanics.

Key Changes

• Creaking Heart API: Added getCreaking() and isActive() to CreakingHeart BlockState, and getCreakingHeart() to Creaking entity for bi-directional connectivity.
• Breeze API: Fully implemented the Breeze interface with getInhaleTicks(), setInhaleTicks(), getJumpCooldown(), setJumpCooldown(), and isJumping().
• Wolf Armor API: Added armor management methods to Wolf entity, including isWearingArmor(), getArmorDurability(), and setArmorDurability().
• Wind Charge API: Enhanced AbstractWindCharge with explosion radius control (getExplosionRadius(), setExplosionRadius()) and origin tracking (isPlayerCreated()).

Rationale

These additions fill significant gaps in the current Paper API for 1.21.4 features. Currently, developers have to rely on NMS or packet interception to access these basic properties. By upstreaming these methods, we improve plugin stability and developer experience across the ecosystem.

All changes follow Paper's coding standards, including JSpecify nullability annotations and proper Javadoc documentation.

Wolf Armor API:

That was already part of the API as entity equipment

Thanks for the feedback! While it is possible to use the generic equipment API, these methods are intended as "convenience methods." They make the new 1.21.4 wolf mechanics much easier to find and use for developers, without requiring manual null-checks or slot management every time.

This seems like a partial duplicate of #12095
The other methods are very much just duplicate API surface, either covered by setYield or the equipment API.
