Update CI to Xcode 15.1 & run builds for iOS, watchOS, tvOS (#231)

- Adds new CI jobs to build the library against macOS, iOS, tvOS, and
watchOS rather than only the default environment (macOS)
- Updates `@available` annotations to properly accommodate these
additional platforms
- Updates CI to use Xcode 15.1

Originally the intent was to run tests on each platform, but for some
reason GitHub runners are refusing to cooperate and jobs are stalling.
Instead, we'll continue running `swift test` which runs tests on the
host environment (macOS) and will use `xcodebuild` to build for each
platform since it allows for specifying a target SDK/environment (see
[this
question](https://stackoverflow.com/questions/60245159/how-can-i-build-a-swift-package-for-ios-over-command-line)
and [these
notes](https://www.jessesquires.com/blog/2021/11/03/swift-package-ios-tests/)).

Follow-up to #227 and
related to #226.
