Christian Blichmann fea5e8c485 CMake: Avoid Google Test error when re-configuring with latest Abseil
Abseil insists on having a Google Test directory, even if we're not going to
run (or even build) the tests.

This changes forces all test settings to `OFF` just for Abseil, allowing
SAPI builds to complete normally. Embedding projects should not be affected,
if they already included Abseil.
