[leptos-null]

What does this implement/fix? Explain your changes.

This PR aims to simplify the process to patch an SDK.

In detail, this PR

• Moves supporting code into tools/ directory (for organizational purpose)
• Reduces create_patched_sdk.sh parameters from 7 to 4
• Removes support for using simulator binaries as source for symbols
  • This has been shown to be erroneous due to the simulator not being the same as real devices
• Uses a fixed set of options to tbd for deterministic results
• Provides create_patched_sdk_image.sh which can patch an SDK using a dyld_shared_cache file
  • This reduces the need for contributors to need physical access to the device they would like to patch an SDK for
• Adds a GitHub Actions workflow to patch a requested SDK
  • Downloads an IPSW
  • Finds the dyld_shared_cache
  • Patches SDK using scripts in tools
  • Pushes a branch with the requested SDK
