[cxx-interop] Support ObjC protocols in C++ interop
...
This patch introduces handling of ObjC protocols similar to how ObjC
classes work. Since this only works in ObjC++, all declarations
containing ObjC protocols will be protected by the __OBJC__ macro.
This patch results in some `_bridgeObjC` methods being exposed, we might
end up hiding those in the future, but there is no harm having them in
the interop header for the interim period.

[cxx-interop] Support generic types with isValueType trait
...
In some circumstances the missing trait resulted in picking the wrong
branch of some compile time conditionals resulting in code that would
not compile.

[cxx-interop] Support optional generic cases in enums
...
This PR implements proper support for optional generic associated values
in enum cases. Most of the code changes are supporting generic types in
more contexts in the printer, the rest are making sure we handle the
null pointer case when we try to get the declaration from the type that
represents a generic parameter.

[Generated header] Emit members of enum extensions into C++ class
...
As we do with Swift structs, emit the members of extensions of Swift
enums into the corresponding C++ class. This includes exposing more of
the Optional API from the standard library into Swift.

[CxxInterop] Change C++ interop header ordering
...
Consider the case of a toolchain that includes clang is being used to
compile Swift. With the current ordering, the header will be found
relative to that toolchain, which could be out of date as compared to
tip. This is the case today if eg. a 5.7 toolchain is used to build
main/5.9 as the shim header is missing a definition.

[interop][SwiftToCxx] Declare the generic usability type trait before the C++ class that represents the Swift type

This allows you to import a method that returns the type of the context in which the method is declared when such
type is a generic parameter in another type. This means that it's now possible to bridge the initializer for
RawRepresentable enums.
