ci(windows): only the pregate tests that pass on windows-latest join the lane

windows-free-tests run 38984824731 (this branch at 8ed6da402) ran the moved
files. gstack-regen and the new pregate-wtree-refusal passed. pregate-guards,
-remote, -regate, -invalidation, -selection and -bats-nested launched
gstack-pregate fine but fail on Linux-host expectations: their fixture lanes are
Linux workflow jobs, which a Windows host records as requires-remote
obligations. They go back to KNOWN_WINDOWS_INCOMPATIBLE with that reason
instead of "shebang via CreateProcess".
