I'm developing a game using WebGL and I'm looking to use WebGL2, but currently Safari doesn't support it. However, the next version of Safari (15), which is set to release this fall via the Monterrey update, will!
However, I'm still not sure whether or not it is a good idea to use WebGL2, considering I am not sure how quickly the support for WebGL2 will convert amongst iOS users.
That is, will only new iPhones be eligible for the latest Safari? Does it automatically update, or manually? And if currently released iPhones are eligible, then what determines how far back eligibility goes? Will iPhones released from several years ago also have access to the latest version of Safari? Also, will Safari 15 release for Desktop and iOS simultaneously?

By determining if the iPhone is capable of running the latest version of iOS. Safari comes bundled with iOS and a version of Safari is tied to the version of iOS running on device.
All the iPhones that support running iOS 15 will be able to run the desired version of Safari. iOS 15 is supported on the following iPhone:
Supported iPhone does not automatically update to iOS 15. They have to be updated with the consent of the user.
Apple decides which model of iPhone to support with the upcoming release of iOS. All the iPhone which ran iOS 13 and iOS 14 are capable of running iOS 15. This included iPhone as far back as iPhone 6s, released in September 2015.
All the iPhone released in the year 2015 and later are capable of running iOS 15.
Only Apple can answer that, but from historical pattern, a new major of iOS/iPadOS and macOS are made around the same time frame. Sometime they get released simultaneously, but the release can also happen a few weeks apart.
