Add watchosDeviceArm64 target

[MatthewFolbigg]

In April 2026 WatchOS will require Arm64 as an architecture.

Whilst watchosArm64() is already listed, I believe it only adds support for Arm64_32.

I believe watchosDeviceArm64() will be required for Arm64

This PR adds watchosDeviceArm64 alongside every reference I could see to watchosArm64

I'm not sure if there are other changes required for this PR!

Looks like you'll need to add this to the whole Apollo Galaxy... It is currently failing on https://github.com/apollographql/apollo-kotlin-mockserver

@martinbonnin I'm working my way around! 😅 apollographql/apollo-kotlin-mockserver#39
Thanks for taking a look at these!

Thanks! I'll backport to 4.x

I'll backport to 4.x

I take that back, 4.x is still on Kotlin 2.1.20 and we can't use 2.2.0 libraries there because of native lack of compatibility flags.

I'll create a new major version of adapters for 5.0
