cryptoauthlib: add cryptoauthlib-test package 

This adds the same example application that was used for the old version of the
library, but it has been separated into a proper package this time.

Recommend said package when installing the library.

Subject: [PATCH 5/6] test: add CMakeLists.txt
This file was ported form the master branch to be able to compile the
cryptoauth_test app. Additional installation instructions were added as well.
Move the ATCA_HAL_I2C build option to the root CMake file to enable it for both
the library and the test app.

Subject: [PATCH 6/6] Remove unnecessary code from cryptoauth_test
Some test commands apply to chips other than the ATECC508A, and can cause
errors when used incorrectly. Remove all code that doesn't apply to our
platforms.
