Deprecate source-login-scripts.sh (expo#18330)

# Why

the `source-login-scripts.sh` introduced a lot of pain where the community reported much build errors from it. it doesn't support shells other than zsh and bash. this pr find a new way to deal with xcode building issues that it cannot find the correct nodejs path.

# How

react-native introduces `.xcode.env` and `.xcode.env.local` for developers to override the `$NODE_BINARY`: facebook/react-native#33546

to make sure building success from expo-constants, expo-updates, and also the app target when generating bundles. i would like to reuse the `.xcode.env` and `.xcode.env.local` from react-native. this pr further generates `.xcode.env.local` automatically for the app during `pod install`. we can ensure that `pod install` is executed from shell and nodejs is available. so we will generate `export NODE_BINARY="$(command -v node)"` in the `.xcode.env.local`. for xcode, the path will be `$PODS_ROOT/../.xcode.env.local`, every xcode subprojects can source the file to get correct `$NODE_BINARY`.

# Test Plan

- building bare-expo from xcode (opening xcode by macos finder)
- building bare-expo by `yarn ios`
- updates e2e ci passed
- building expo-go (prerequisite: expo#18344)
