Update git submodules

* Update docs/submodules/apex from branch 'master'
  - Adding conditionals dependent on arch

    There are x86 specific build items that can't be used when building on
    aarch64. Adding conditionals so that the items only get built in when
    building on x86_64.

    There are aarch64 specific settings that need to be set for deployment.
