build.ps1: allow querying a specific SDK from the pinned toolchain

compnerd · compnerd · commit 75a6d101403f · 2025-08-11T15:43:04.000-07:00
This allows us to use a specific SDK from the pinned toolchain image. By
enabling this functionality, we can migrate towards a newer snapshot and
build the early swift-driver.
