[InterfaceGen] Print property initializers in resilient, fixed-layout types (#19619)

Browse Source 
Augment the ASTPrinter to print the name and text of initializer expressions if
a property has an initializer and the type is @_fixed_layout and resides in a resilient module, and serialize the text for partial modules.

With this change, all .swiftinterface files in the project (except for SwiftLang) compile to swiftmodules on macOS.
