Support repeat window resize action

[CWEzio]

Is your feature request related to a problem? Please describe.
Currently, I can use commands like c-w + > to resize the window. However, to increase the size change, I have to repeated type c-w + [key] commands, which is a bit of tedious.

Describe the solution you'd like
It would be nice to be able to repeat the resize window action. For example, c-w + 3 + > will resize the window for three times. This is supported in vim.

Additional context
This issue has been raised in issue #2044, this commend. However, that issue has been closed and it seems that this commend went unnoticed. Therefore, I create a new issue here. Another not implemented feature mentioned in this commend is that c-w _ to maximize the current pane's height and c-w | to maximize the current pane's width.

Besides, the resize window feature c-w + > hasn't been mentioned in roadmap.

Why not using something like this?:

{
      "key": "ctrl+shift+-",
      "command": "workbench.action.decreaseViewSize"
   },
   {
      "key": "ctrl+shift+=",
      "command": "workbench.action.increaseViewSize"
   }

No interruption with other shorcuts. And you will get even more control over the size window cause you can hold the keys and adjust the window to your need... If u use something like c-w + 3 + > and u don't like it, you should run again the command

This is a nice workaround. However, since commands like c-w + 3 + > is the vim native command, I think it would be good for vscode-vim to also support this command.
