Blocks: Allow for nested `the_content` calls within `do_blocks()`.

When `do_blocks()` is run, it sets up some special handling of the `wpautop` filter, as we don't want `wpautop` to run on block content, but we do want it to be available for subsequent runs of `the_content`, which may be happening on non-block content.

As we set this up before rendering dynamic blocks, however, a dynamic block choosing to run `the_content` will cause unintentially structural deficiences in this particular recursive block tower.

Moving this handling to after dynamic blocks are rendered makes our tower lean a little less.

Props aldavigdis, pento.
Fixes #45495.
