* Move test libraries to lib dir

* Move test linking to a new option chip_link_tests

Zephyr doesn't link test executables during the CHIP build, and instead
consumes the test static libraries produced by the build using its own
build system. Move this mode to a new named option "chip_link_tests".

Android shouldn't link executables, either, because native code on that
platform is always run JNI shared libraries. It could link shared
libraries, however as this is not yet implemented, just turn off linking
for now.

* Use GN to build ESP32 qemu tests

* Ignore libChipCryptoTests

These tests do not work.

* Fix comment

* Cleanup

* Restyle
