Subject: [PATCH 1/3] Add support for `"multiple": false` block types

If the `block.json` configuration for a block specifies
`"multiple":false`, then only a single instance of that block
should be allowed in a post. If the block already exists in the
post, the option to add that block again will be disabled.
