18817b82 - [Concurrency] NonisolatedNonsendingByDefault: Extend `nonisolated(nonsending)` to `withoutActuallyEscaping`

[Concurrency] NonisolatedNonsendingByDefault: Extend `nonisolated(nonsending)` to `withoutActuallyEscaping` `withoutActuallyEscaping` is type-checked in a special way which means that we need to explicitly inject `nonisolated(nonsending)` isolation when forming a reference to this builtin. (cherry picked from commit 48f4d7b688c325a0b7d5a8721576d5bc46fa0c1d)
