Swift: Support static-library try-compile type

Browse Source 
Top-level code only works as part of executables, which breaks when
`CMAKE_TRY_COMPILE_TARGET_TYPE` is set to `STATIC_LIBRARY`. This patch
fixes the test to something agnostic between executables and libraries
while still verifying that we can import types from the standard
library.

Fixes: #25984
