[gha] fix the Windows Swift toolchain build (#899)

* GHA: tweak the library naming for static libraries

This was changed upstream to use `lib` prefix for static libraries on
Windows for Swift. Apply the necessary build changes to ensure that the
build system is aware of this.

* include cmake_linker_flags when building Windows tools

* remove extra CMAKE_STATIC_LIBRARY_PREFIX_Swift
