Subject: [PATCH] build: adopt static linking for Yams on Windows toolchain

Windows now partially supports static linking of Swift libraries
(non-swiftCore targets).  Use this to enable static linking of Yams as
there is a single user (swift-driver).  This allows us to save ~256KB
due to the internalisation.
