Retrieving VMware Workstation VM encryption passwords saved in the the Windows Credential Manager

When creating an encrypted VM, VMware Workstation gives you the option to remember the password. It does this by storing the password in the Windows Credential Manager.

VMware does not provide a way to retrieve this stored password, but it can be accessed via the Win32 CredReadW API function.

This PowerShell example has been tested using Windows PowerShell (v5.1) and PowerShell (v7) using VMwa

## include to support waveform dumping with SIM=<vcs|icarus|verilator>

## For vcs:
## 	To select between *.vcd and *.vpd waveform dumps, set WAVES=<VCD|VPD>
## 	variable. This variable can be an environmental varaiable, a variable
