[TASK] Move up getAllDeclarationBlocks to CSSBlockList

[oliverklee]

Move this method up without any changes to the method or its callers.

We'll clean this up in later changes.

Part of #994.

[oliverklee]

Waiting for #991 to be merged first as there will probably be merge conflicts.

The names of the moved test methods don't match those finally agreed upon in #991.

This PR here is about getAllDeclarationBlocks. #991 is about getAllRuleSets.

I propose we align the names of the tests for getAllDeclarationBlocks with those for getAllRuleSets in a separate PR.

OK. But the getAllRuleSets tests seem to be being removed in this PR.

Oh, that shouldn't have happened. Hold on …

Fixed now. Good catch!

This PR here is about getAllDeclarationBlocks. #991 is about getAllRuleSets.

I originally thought that the tests had been renamed from #991, since I was looking at the removed getAllRuleSets tests and failed to spot that the moved tests were those for getAllDeclarationBlocks.

I've checked more thoroughly now and confirm that the only difference in the moved tests is the subject now being a ConcreteCSSBlockList rather than a Document.
