When blocks were initially implemented, they were represented as containers in the i18n AST. This is problematic, because block affect the structure of the message. These changes introduce a new `BlockPlaceholder` AST node and integrate it into the i18n pipeline. With the new node blocks are represented with the `START_BLOCK_<name>` and `CLOSE_BLOCK_<name>` placeholders. PR Close #52958
