Document generate_bundle=yes SCons option in Compiling for macOS and iOS

- Reorder instructions to mention ARM64 builds first in macOS,
  as this is the primary architecture in use now (with all new Macs
  since 2023 being sold with Apple Silicon only). The `lipo` command still
  works as before, as it infers the architecture from the input files.
- Remove the manual bundle generation steps to make the page shorter
  (similar to Compiling for Android).
- Remove references to the master branch (this was only relevant when
  4.0 was still in development).
