Apple TV support 1: podspec and code changes for commonly used modules (#24329)

# Why

First of a series of PRs to add Apple TV support for many (but not all)
Expo SDK modules.

This PR makes Apple TV able to compile for apps using
`[email protected]` and ONLY the following modules:

- expo
- expo-application
- expo-constants
- expo-eas-client
- expo-file-system
- expo-font
- expo-json-utils
- expo-keep-awake
- expo-manifests
- expo-modules-core
- expo-splash-screen
- expo-structured-headers
- expo-updates-interface
- expo-updates

# How

- Add tvOS to podspecs
- Native code changes wrapped in `#if TARGET_OS_TV` (for Objective C) or
`#if os(tvOS)` (for Swift)
- Import source for the `ASN1Decoder` Swift framework used by
`expo-updates`, as the public podspec for that framework does not yet
support tvOS

# Test Plan

- Manual testing with a template still in development
- Existing CI for iOS should pass (nothing should be broken)
