Support `visionOS`

We'd like to support the visionOS as SDK option when compiling with XCode.

This should probably ~~either~~ be another OS ~~or another IOSSdk~~:

We need this in:

• [ ] package:native_assets_cli so that it can be passed in from flutter_tools and consumed in build.dart scripts.
• [ ] package:native_assets_builder so that it can be passed in from flutter_tools.
• [ ] package:native_toolchain_c so that the right SDK path is passed when compiling C code.

or another IOSSdk

It's not an iOS SDK, it's the visionOS SDK, which is a different SDK.

Did you manage to find a solution for this?

This isn't a "find a solution" kind of issue, it's a "do the work of adding all of the plumbing" kind of issue. There's not going to be a trick or shortcut, it something that has to be worked through methodically.

To clarify, there's no point in adding support in the native assets feature, which this issue is tracking, if Flutter doesn't have support yet:

Nice! Thank you guys for the quick response. I am trying to understand the work that needs to be done for visionOS support and when I tried to run it through xcode it got me here
