Adds styles for individual core blocks to make it possible to render only styles for those blocks that are rendered on the page (frontend). This is optinal functionality for start that can be controlled with the new `separate_core_block_assets` filter.
In addition to that, styles can be inlined when `path` is passed when registering an individual styles. This functionality can be changed with the new `styles_inline_size_limit` filter. The maximum size of inlined styles in bytes defaults to 20 000.
