[InterfaceGen] Print private/internal properties (#19127)

Browse Source 
* [Interface] Print private/internal properties

All properties which contribute to the storage of a type should be
printed, and their names should be hidden from interfaces. Print them
with '_' as their name, and teach the parser to recognize these special
patterns when parsing interface files.

Partially resolves rdar://43810647

* Address review comments

* Disable accessor generation for nameless vars

* Test to ensure interface files preserve type layout

* Ignore attribute differences on Linux
