function DrupalKernelTest::testBuildParametersRemoved

Tests that dot-prefixed build parameters are removed from the container.

Build parameters (e.g. '.hook_data') are used to pass data between compiler passes. RemoveBuildParametersPass strips them so they don't bloat the cached container definition with data that is only needed at build time.
