function TestEmptyBlock::build
Builds and returns the renderable array for this block plugin.
If a block should not be rendered because it has no content, then this method must also ensure to return no content: it must then only return an empty array, or an empty array with #cache set (with cacheability metadata indicating the circumstances for it being empty).
Return value
array A renderable array representing the content of the block.
