[interop][SwiftToCxx] annotate several value members types as 'noexcept'
...
C++/clang is more strict about requiring noexcept in templates so we need some explicit annotations

[interop][SwiftToCxx] annotate inline thunks with SWIFT_INLINE_THUNK
...
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.

[interop][SwiftToCxx] Annotate emitted declarations with Clang's external_source_symbol attribute
...
Each emitted declaration is annotated with the external_source_symbol with its own USR, to allow Clang's indexer to recognize this declaration as a Swift declaration with a specific USR
