[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relative to that toolchain, which could be out of date as compared to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.

This macro applies always_inline in addition to inline. It also applies artificial, which lets debugger know that this is an artificial function. The used attribute is added in debug builds to ensure that the symbol is emitted in the binary so that LLDB can invoke it.

This is done by exposing nested Index and UTF8View type in String. Nested types aren't

[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.
