Fix: Link Crypt32.lib for firebase_analytics_test on Windows

I've added Crypt32.lib to the dependencies of the firebase_analytics_test
target in `analytics/tests/CMakeLists.txt` when building on Windows.

This is to resolve a persistent LNK2019 error for
_CryptBinaryToStringA@20, which occurs during the linking phase of
firebase_analytics_test.obj. This change directly links the
required system library at the test executable level.
