Blocks: Add the `pre_render_block` and `render_block_data` filters. 

At the start of `render_block()`, the `pre_render_block` filter allows the function to be short-circuited, and the `render_block_data` filter is applied to the `$block` parameter before it's processed.

Props kkarpieszuk, pento.
Fixes #45451.
