The details

Resolves

#6079 and problems introduced in #6174

Proposed Changes

Types all of the generators as any instead of Blockly.Generator. They used to be effectively any before (because they were broken), and typing them as Generator is incomplete because there are additional properties on each generator that aren't captured. So giving them a partial type is worse than any because there are additional type errors that would have to be silenced.

Same for the BlockDefinition which is used for Blockly.Blocks - it was typed as Object but even that is too strict as e.g. Objects don't have a property called jsonInit which we allow objects in Blockly.Blocks to have.
