To achieve this, add a new cache variable
`SWIFT_EMBEDDED_STDLIB_SDKS_FOR_TARGET_TRIPLES` to be set like in the
following examples.
```
-DSWIFT_EMBEDDED_STDLIB_SDKS_FOR_TARGET_TRIPLES=aarch64-vendor-os@/usr/local/aarch64-vendor-os-sdk;aaarch-vendor-anotheros@/opt/aarch64-vendor-anotheros-sdk
```
We chose to use another setting instead of e.g. folding this into
`SWIFT_EMBEDDED_STDLIB_EXTRA_TARGET_TRIPLES` so it is clear this is opt
in and it does not regress existing configurations that set the SDK
directly (like it's the case for the WASM stdlib).
