Add BlockType.INLINE support #2

[yuri-kiss]

Resolves

Nothing is resolved this is just a new feature.

Proposed Changes

Adds BlockType.INLINE support in full (so compiler support)
This takes the second approach of #187 (comment)
And this PR can be used as a replacement for #187 itself.

Reason for Changes

The need for ugly inline patches and hacky thread stuff.

Test Coverage

No tests but I did try with a extension.

(function(Scratch) {
  class InlineBlockTest {
    getInfo() {
      return {
        id: 'InlineBlockTest',
        name: 'Test: Inline Block',
        blocks: [{
          blockType: Scratch.BlockType.INLINE,
          opcode: 'block',
          text: 'inline',
        }]
      }
    }
    async block(_, util) {
      await (Promise.resolve());
      util.startBranch(1, true); // Loop does not actually work like "loop"
      return 'test';
    }
  }
  Scratch.extensions.register(new InlineBlockTest);
})(Scratch);

Currently util.startBranch with the loop parameter as true does not actually make it a loop, I dont know how to fix this while still allowing a return value.

And honestly I don't see a practical reason for the block to be a loop anyways but I did attempt to support it with no avail, the return value was able to be grabbed but without using globalState.blockUtility._startedBranch[0] I cant get the branch from what I know.

If this does not matter I can resolve this, I just wanted to point it out to you. (garbomuffin)
