github actions: include current macOS / iOS builders

[cscd98]

Guidelines

1. Rebase before opening a pull request
2. If you are sending several unrelated fixes or features, use a branch and a separate pull request for each
3. If possible try squashing everything in a single commit. This is particularly beneficial in the case of feature merges since it allows easy bisecting when a problem arises
4. RetroArch codebase follows C89 coding rules for portability across many old platforms check using C89_BUILD=1

Description

Adds Apple builders for the current metal and IOS project
Removes xpretty because that hides the debug information I actually need
Note: iOS does not produce a artifact due to no credentials in github

This is useful for me as I do not own a macbook to compile with so I can see failures and correct them.
