  [Cocoa] Create a platform abstraction for process capabilities
https://bugs.webkit.org/show_bug.cgi?id=264986

Reviewed by Per Arne Vollan.

In 269791 at main we adopted _SECapabilities to take process assertions on iOS. In a follow-on change
we will adopt a new kind of process capability, so in preparation this change creates a platform
abstraction around the concept of process capabilities. This will allow us to more easily create new
types of capabilities and write tests.

For now, this change creates an abstract ProcessCapability class that can return a platform
capability (_SECapabilities on iOS), creates an AssertionCapability subclass that vends the type of
platform capability adopted in 269791 at main, and uses it in ProcessAssertionCocoa.
