Add a function "workspace.refresh()"

i was unable to refresh workspace after reinitialize a block by Blockly.Blocks['a'] then i found out that blocks inside workspace don’t update but blocks inside toolbox are updating fine so, we need to refresh workspace after reinitializing a block. As mentioned at https://github.com/google/blockly/issues/3940#issuecomment-640267246

1. A solution for refreshing workspace

   1. export xml of blocks
   2. clear the workspace
   3. reimport blocks from xml

2. A solution to refresh toolbox by using workspace.refreshToolboxSelection()

Now we can add a function workspace.refresh() something like

Blockly.Workspace.prototype.refresh = function() {
    var xml = Blockly.Xml.workspaceToDom(this);
    this.clear();
    Blockly.Xml.domToWorkspace(xml, this);
    this.refreshToolboxSelection();
};

Thanks @BeksOmega for pointing me in the right direction. I just realized I had my workspace variable declared as Workspace instead of WorkspaceSvg and that method wasn’t working when I tried it first. I fixed it and I am now using Blockly.svgResize and it works as expected.

Hello @genemars ! This issue is slightly different from resizing the workspace. The person in this issue wanted all of the blocks on the workspace to update when they modified the block definition, which we do not generally want to support.

However, if you want to resize the workspace that is definitely supported. You can call Blockly.svgResize(myWorkspace). I hope that helps!
