fix(ios): make Podfile.lock SPEC CHECKSUMS deterministic across machines

Two sources of non-determinism cause Podfile.lock to differ between
machines, breaking `pod install --deployment` in CI:

1. Yoga.podspec: Dir.glob returns files in filesystem-dependent order.
   Add .sort to ensure consistent ordering regardless of OS/filesystem.

2. hermes-engine.podspec: require.resolve with __dir__ produces an
   absolute path containing the user's home directory. Replace with a
   $(PODS_ROOT)-relative path that resolves at build time instead.

Fixes #56975
