aa61d953 - [embedded] Allow disabling embedded stdlib, but still test compiler (#73977)

[embedded] Allow disabling embedded stdlib, but still test compiler (#73977) While one can disable building the embedded stdlib, the tests for that feature were unconditionally added. If one wants to just build the compiler without any stdlib (except target), a bunch of embedded tests would have failed. Inject the value of `SWIFT_SHOULD_BUILD_EMBEDDED_STDLIB` into the Lit test system as a feature `embedded_stdlib` and add `REQUIRES:` to a couple of tests outside the `embedded/` directory that seems to use the experimental feature. Make the tests in `embedded/` unsupported in the local Lit configuration file.
