cmake: library: Add custom targets for generated files

Add a custom target that depends on TLS
generated files, and make both the static and
shared crypto libraries depend on it.

This ensures that when both libraries are built,
the files are not generated concurrently
by the static and shared library targets.

Do the same for the x509 libraries.
