Different cursor shape to indicate that a normal mode command is in the middle of being typed out

Is your feature request related to a problem? Please describe.
In (actual) vim, when you press the first key of a multi-key normal mode command, such as d, the cursor changes from block to half-height-block. This is a useful visual indicator that a command has begun. When the command is complete, the cursor changes from half-block to full-block; this is a useful visual indicator that the command has been completed. Ideally VSCodeVim would allow the cursor to take on a different shape for the duration of a command.

Describe the solution you'd like
Ideally VSCodeVim would allow the cursor to change shape when a normal mode command has begun, and change it back when the command has completed. I imagine only VSCode-supported cursor shapes would be possible, so no half-height cursor, but even having the cursor switch from block to block outline would still be an improvement.

Describe alternatives you've considered
An indicator more prominent than the partially typed command in the command line.

Additional context
Cursor is in the top left corner. In the second image it's half-height in response to me pressing d.

The issue provides no file, test, or entry point to begin from. Start by locating how VSCodeVim tracks partially typed normal-mode commands and how it configures the VS Code cursor shape; compare the available cursor styles with the requested state transition. Done means the cursor visibly changes while a command is incomplete and returns to its normal shape when the command completes.
