659d1cfb13 Make ObjC isEqual: delegate to Equatable when Hashable isn't available 
When a Swift struct gets bridged to Obj-C, we box it into an opaque
`_SwiftValue` Obj-C object.  This object previously supported the
Obj-C `isEqual:` and `hash` selectors by dispatching to the Swift
Hashable conformance, if present.

This does not work if the Swift struct conforms to Equatable but
does not conform to Hashable.  This case seems to have been
overlooked in PR #4124.

This PR extends the earlier work to support `isEqual:` by
first checking for a Hashable conformance, then falling back
on an Equatable conformance if there is no Hashable conformance.

ae2e903574 [embedded] Build an initial embedded Swift standard library 
This isn't a "complete" port of the standard library for embedded Swift, but
something that should serve as a starting point for further iterations on the
stdlib.

- General CMake logic for building a library as ".swiftmodule only" (ONLY_SWIFTMODULE).
- CMake logic in stdlib/public/core/CMakeLists.txt to start building the embedded stdlib for a handful of hardcoded target triples.
- Lots of annotations throughout the standard library to make types, functions, protocols unavailable in embedded Swift (@_unavailableInEmbedded).
- Mainly this is about stdlib functionality that relies on existentials, type erasure, metatypes, reflection, string interpolations.
- We rely on function body removal of unavailable functions to eliminate the actual problematic SIL code (existentials).
- Many .swift files are not included in the compilation of embedded stdlib at all, to simplify the scope of the annotations.
- EmbeddedStubs.swift is used to stub out (as unavailable and fatalError'd) the missing functionality.
