scripts: add command line options to override googletest build options

These new command line options can be used for CI without having to configure googletest's optons in the
known-good.json. Useful when building vkconfig staticly for CI.

scripts/update_deps.py:
- add 2 new options `---gtest-shared-libs` and `--gtest-force-shared-crt`
that allows a user to specify values for googletest cmake build
options "BUILD_SHARED_LIBS" and/or "gtest_force_shared_crt"
