Allow refreshBlocks() to specify extension

[FurryR]

Resolves

The base of dynamic blocks.

Proposed Changes

Added a optional parameter to refreshBlocks, allowing specify which extension to refresh.

Reason for Changes

Performance considerations. This change was originally made by Gandi IDE, used for dynamic blocks (maybe), and I think we also need one.

Test Coverage

N/A. No tests for refreshBlocks found.

Oh this'd be amazing

Works as intended. No issues with existing category's or extensions occurred during testing.

Testing extension
Af of now pressing any of these buttons would refresh ALL of the extensions updating the labels and count for every extension, on this pr it only does it for the individual extension you choose to refresh.

(function(Scratch) {
  let countA = -1;
  class extensionA {
    getInfo() {
      return {
        id: '0znzwRefTest1',
        name: 'Refresh Test (A)',
        blocks: [{
          blockType: Scratch.BlockType.LABEL,
          text: `Extension refreshed ${++countA} times`,
        }],
      };
    }
  }
  let countB = -1;
  class extensionB {
    getInfo() {
      return {
        id: '0znzwRefTest2',
        name: 'Refresh Test (B)',
        blocks: [{
          blockType: Scratch.BlockType.LABEL,
          text: `Extension refreshed ${++countB} times`,
        }],
      };
    }
  }
  class extensionC {
    getInfo() {
      return {
        id: '0znzwRefTest3',
        name: 'Refresh Test (C)',
        blocks: [{
          blockType: Scratch.BlockType.LABEL,
          text: `Extensions refreshed total ${(countA + countB)} times`,
        }, {
          blockType: Scratch.BlockType.BUTTON,
          func: 'refreshALL',
          text: 'Refresh all',
        }, {
          blockType: Scratch.BlockType.BUTTON,
          func: 'refreshA',
          text: 'Refresh (A)',
        }, {
          blockType: Scratch.BlockType.BUTTON,
          func: 'refreshB',
          text: 'Refresh (B)',
        }, {
          blockType: Scratch.BlockType.BUTTON,
          func: 'refreshC',
          text: 'Refresh (C)',
        }],
      };
    }
    refreshALL() {
      Scratch.vm.extensionManager.refreshBlocks();
    }
    refreshA() {
      Scratch.vm.extensionManager.refreshBlocks('0znzwRefTest1');
    }
    refreshB() {
      Scratch.vm.extensionManager.refreshBlocks('0znzwRefTest2');
    }
    refreshC() {
      Scratch.vm.extensionManager.refreshBlocks('0znzwRefTest3');
    }
  }
  Scratch.extensions.register(new extensionA());
  Scratch.extensions.register(new extensionB());
  Scratch.extensions.register(new extensionC());
})(Scratch);

do you have any complaints about making unknown extensions be an error instead of silently ignoring it and refreshing all the extensions ?

Nope, I think it should error as it clarifys things more
