Fix whitespace and indentation in the Compressed compiler.

Before this change the Compressed compiler errored when processing @page and
@supports blocks, and the tests did not cover this.

This change fixes @page and @supports compression in the Compressed compiler,
fixes the tests to fully flex the Compressed compiler, and adds missing fixtures
to flesh out the test suite.
