Christian Blichmann 839914d6dd cmake: Rename build options to follow Abseil naming
`BUILD_TESTING` is a CMake provided option and we should use similar naming,
just like how Abseil does it.

- `SAPI_ENABLE_TESTS` -> `SAPI_BUILD_TESTING`
- `SAPI_ENABLE_CONTRIB_TESTS` -> `SAPI_CONTRIB_BUILD_TESTING`
- `SAPI_ENABLE_EXAMPLES` -> `SAPI_BUILD_EXAMPLES`

Drive-by:
- Fix option name in GitHub action
