Message:

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.
