GHA/windows: set VCPKG_APPLOCAL_DEPS=OFF for vcpkg jobs
Add the necessary directory to `PATH` instead.

To disable a vcpkg feature (auto-copying DLL dependencies next to the
build targets) that was causing CI flakiness in the libssh2 repository.
In curl it currently cannot cause flakiness because targets (with DLL
dependencies) reside in separate directories.

AFAIU this vcpkg feature has been present and enabled by default for
a long time, but only a recent update made it visible in the log and
flaky at the same time, due to switching implementation.

This patch removes log noise and potential issues, improves efficiency,
and saves disk space: 74MB -> 71 in UWP, and 69MB -> 65 in the arm64 job.
Time saving is negligible with current jobs.
