Fix: Link Crypt32.lib for firebase_analytics on Windows

Add Crypt32.lib to the linked libraries for the firebase_analytics
target on Windows. This resolves a linker error LNK2019 for
_CryptBinaryToStringA@20, which was occurring in builds that
included analytics_windows.obj (e.g., firebase_analytics_test).

While CryptBinaryToStringA is not directly called in
analytics_windows.cc, the linker indicates that analytics_windows.obj
requires this symbol, possibly due to an indirect dependency or
other build system interactions. Linking Crypt32.lib provides the
necessary symbol.
