Move the @wordpress/blocks types defined in #48604 into own branch.

[ryanwelcher]

What?

• Part of Convert packages to TypeScript #67691.
• Based on feature: add TypeScript types to the blocks package #48604.

This PR moves only the types from #48604 into a branch in this repo rather than in a fork. This is all of @johnhooks work with the exceptions of some small linting changes required to commit.

This branch can be merged into trunk or used as a feature branch to make small iterations to the package to introduce the types.

Why?

@johnhooks did a lot fantastic work defining the types and while the direction of that PR has changed, it would be a shame to lose that work as we move towards adding Typescript support to the blocks and block-editor packages.

• Adds blocks as a project reference in core-data, block-library, and block-editor
• Populates packages/blocks/src/types with all block-related type definitions and updates package.json to include "types": "build-types"

packages/blocks/src/types/block-variation.ts:7

• Only BlockExampleInnerBlock is used in this file; the BlockType import can be removed to reduce unused code.

import type { BlockExampleInnerBlock, BlockType } from './block-type';

packages/blocks/src/types/block-supports.ts:348

• Most support properties in BlockSupports are optional; consider making shadow, dimensions, position, and __experimentalSelector optional (?) for consistency and to avoid requiring them on every block.

shadow: any;

[Copilot]

The import of BlockType is not used in this file and can be removed to clean up unused imports.

Suggested change

import type { BlockType } from './block-type';

[Copilot]

The import of BlockType is unused here; consider removing it to avoid dead imports.

Suggested change

import type { BlockType } from './block-type';

[Copilot]

The BlockType import isn't referenced anywhere in this module; you can safely remove it.

Suggested change

import type { BlockType } from './block-type';
